Syntax

public static class CultureInfoExtensions

Properties

LegacyLanguageCodeMapping

Gets a mapping from legacy language codes to .Net language codes. The mapping maps from legacy language codes as they are used by SDLX and Trados Translator's Workbench and related applications to the closest language code used by .Net.

This is an internal data structure which should not be directly used and not be modified. To look up a legacy code, use GetMappedCultureCodeForLegacyCode(String).

Declaration

public static Dictionary<string, string> LegacyLanguageCodeMapping { get; }

Property Value

Type	Description
System.Collections.Generic.Dictionary<System.String, System.String>

Methods

AreCompatible(CultureInfo, CultureInfo)

Checks whether two cultures (languages) are compatible. Two cultures are compatible if they denote the same language which means they have to be identical or their closest region-neutral parents are identical.

Declaration

public static bool AreCompatible(CultureInfo c1, CultureInfo c2)

Parameters

Type	Name	Description
System.Globalization.CultureInfo	c1
System.Globalization.CultureInfo	c2

Returns

Type	Description
System.Boolean

GetCultureInfo(Int32)

Returns the culture which corresponds to the specified LCID. If the LCID is unknown or invalid, an exception is thrown. Note that this will also be the case for custom cultures, which seem to always get the same LCID (4096).

Declaration

public static CultureInfo GetCultureInfo(int lcid)

Parameters

Type	Name	Description
System.Int32	lcid	The locale identifier (lcid)

Returns

Type	Description
System.Globalization.CultureInfo	A CultureInfo object, or throws for unknown LCIDs.

GetCultureInfo(Int32, Boolean)

Returns the culture which corresponds to the specified locale, which may be a legacy LCID used internally by SDLX or Trados Translator's Workbench.

Declaration

public static CultureInfo GetCultureInfo(int lcid, bool returnNullForUnknowns)

Parameters

Type	Name	Description
System.Int32	lcid	The locale identifier (lcid)
System.Boolean	returnNullForUnknowns	If true, null is returned for unknown languages. Otherwise, an exception is thrown. This will also be the case if the lcid represets a custom culture (in most cases, the lcid will be 4096 in this case).

Returns

Type	Description
System.Globalization.CultureInfo	A System.Globalization.CultureInfo object, or null if returnNullForUnknowns is true.

GetCultureInfo(String)

Similar to System.Globalization.CultureInfo.GetCultureInfo(System.String), but covers culture names (<language-code>-<region-code>) which are used by SDLX and Trados Translator's Workbench, but have a different code in .Net.

Use this method to transparently map language codes (current and legacy ones) to cultures, for example when processing TTX, ITD, or TMX.

Declaration

public static CultureInfo GetCultureInfo(string name)

Parameters

Type	Name	Description
System.String	name	The culture code

Returns

Type	Description
System.Globalization.CultureInfo	A CultureInfo object, using appropriate fallbacks for backwards compatibility. Throws an exeption if neither the fallback heuristics nor .Net can resolve the culture name.

Remarks

To avoid an exception to be thrown, and to get null for unknown culture codes, use GetCultureInfo(String, Boolean).

GetCultureInfo(String, Boolean)

Similar to System.Globalization.CultureInfo.GetCultureInfo(System.String), but covers culture names (<language-code>-<region-code>) which are used by SDLX and Trados Translator's Workbench, but have a different code in .Net.

Use this method to transparently map language codes (current and legacy ones) to cultures, for example when processing TTX, ITD, or TMX.

Declaration

public static CultureInfo GetCultureInfo(string name, bool returnNullForUnknowns)

Parameters

Type	Name	Description
System.String	name	The culture code
System.Boolean	returnNullForUnknowns	If true, null is returned for unknown culture codes. If false, an exception is thrown if the culture code cannot be resolved.

Returns

Type	Description
System.Globalization.CultureInfo	A CultureInfo object, using appropriate fallbacks for backwards compatibility, or null if the culture code cannot be resolved and returnNullForUnknowns is true.

GetLanguageGroupID(CultureInfo)

Returns the CultureInfoExtensions.LanguageGroupID associated with the specified culture.

Declaration

public static CultureInfoExtensions.LanguageGroupID GetLanguageGroupID(CultureInfo culture)

Parameters

Type	Name	Description
System.Globalization.CultureInfo	culture

Returns

Type	Description
CultureInfoExtensions.LanguageGroupID

GetLanguageGroupName(CultureInfo)

Returns the name of the language group for the specified culture as a string.

Declaration

public static string GetLanguageGroupName(CultureInfo culture)

Parameters

Type	Name	Description
System.Globalization.CultureInfo	culture	The culture (may not be null)

Returns

Type	Description
System.String	The name of the language group the culture belongs to, or null if the group is unknown.

GetLeadingClitics(CultureInfo)

Returns a case-sensitive string hash set containing the leading separable clitics for the provided culture, or null if none are defined.

Declaration

public static HashSet<string> GetLeadingClitics(CultureInfo culture)

Parameters

Type	Name	Description
System.Globalization.CultureInfo	culture

Returns

Type	Description
System.Collections.Generic.HashSet<System.String>

GetMappedCultureCodeForLegacyCode(String)

Assumes the passed culture code is a legacy code and returns the mapped equivalent. null is returned if no mapping exists (which means that the code is not a legacy code or no mapping is required or yet specified).

Declaration

public static string GetMappedCultureCodeForLegacyCode(string legacyCode)

Parameters

Type	Name	Description
System.String	legacyCode

Returns

Type	Description
System.String

GetRegionNeutralCulture(CultureInfo)

Computes and returns the region-neutral parent culture of the input culture. If the input culture is already neutral, it is returned. Otherwise, the parent culture hierarchy is traversed until a region-neutral culture is found.

Declaration

public static CultureInfo GetRegionNeutralCulture(CultureInfo culture)

Parameters

Type	Name	Description
System.Globalization.CultureInfo	culture	The input culture

Returns

Type	Description
System.Globalization.CultureInfo	The region-neutral parent culture of the input culture

Remarks

A region-neutral culture is not necessarily one "without dashes". For example, the region-neutral parent culture of zh-CN (Chinese, PRC) is zh-CHS or zh-Hans (Simplified Chinese). The exact result may depend on the operating system version and the .Net version.

GetRegionQualifiedCulture(CultureInfo)

Heuristically computes and returns the region-specified ("default") culture for a given language. If the input culture is not neutral (i.e. it is region-specific), it is returned. Otherwise the method will find the region-qualified culture which most likely represents the culture's default/major region.

Declaration

public static CultureInfo GetRegionQualifiedCulture(CultureInfo culture)

Parameters

Type	Name	Description
System.Globalization.CultureInfo	culture	The input culture

Returns

Type	Description
System.Globalization.CultureInfo	The input parameter, if it's a region-qualified/non-neutral culture, or the default region-qualified culture otheriwise.

GetRegionQualifiedCulture(String)

Heuristically computes and returns the region-specified ("default") culture code for a given language code. If the input culture is not neutral or does not have a region-qualified equivalent, null is returned.

Declaration

public static string GetRegionQualifiedCulture(string cultureCode)

Parameters

Type	Name	Description
System.String	cultureCode

Returns

Type	Description
System.String

GetTrailingClitics(CultureInfo)

Returns a case-sensitive string hash set containing the trailing separable clitics for the provided culture, or null if none are defined.

Declaration

public static HashSet<string> GetTrailingClitics(CultureInfo culture)

Parameters

Type	Name	Description
System.Globalization.CultureInfo	culture

Returns

Type	Description
System.Collections.Generic.HashSet<System.String>
