IExpandoResourceManagerGetMetaStream Method

Returns a MemoryStream instance from the metadata of the specified name and culture.

Definition

Namespace: KGySoft.Resources
Assembly: KGySoft.CoreLibraries (in KGySoft.CoreLibraries.dll) Version: 8.1.0
C#
MemoryStream? GetMetaStream(
	string name,
	CultureInfo? culture = null
)

Parameters

name  String
The name of the metadata to retrieve.
culture  CultureInfo  (Optional)
An object that represents the culture for which the metadata should be returned. If this value is , the CultureInfo object is obtained by using the CultureInfo.InvariantCulture property. Unlike in case of GetStream method, no fallback is used if the metadata is not found in the specified culture. This parameter is optional.
Default value: .

Return Value

MemoryStream
A MemoryStream object from the specified metadata, or if name cannot be found in a resource set.

Remarks

Depending on the value of the CloneValues property, the GetMetaObject method returns either a full copy of the specified metadata, or always the same instance. For memory streams none of them are ideal because a full copy duplicates the inner buffer of a possibly large array of bytes, whereas returning the same stream instance can cause issues with conflicting positions or disposed state. Therefore the GetMetaStream method can be used to obtain a new read-only MemoryStream wrapper around the same internal buffer, regardless the current value of the CloneValues property.

GetMetaStream can be used also for byte array metadata.

If SafeMode is and name is neither a MemoryStream nor a byte array metadata, then instead of throwing an InvalidOperationException the method returns a stream wrapper for the same string value that is returned by the GetString method, which will be the raw XML content for non-string metadata.

Exceptions

ArgumentNullExceptionname is .
ObjectDisposedExceptionThe IExpandoResourceManager is already disposed.
InvalidOperationExceptionSafeMode is and the type of the metadata is neither MemoryStream nor byte[].
MissingManifestResourceExceptionNo usable set of localized resources has been found, and there are no default culture resources. For information about how to handle this exception, see the notes under Instantiating a ResXResourceManager object section of the description of the ResXResourceManager class.
