IMetaDataImport::GetCustomAttributeByName method

Gets the custom attribute, given its name and owner.

Syntax

C++


HRESULT GetCustomAttributeByName(
  [in]                       mdToken tkObj,
  [in]                       LPCWSTR szName,
  [out, size_is(, *pcbData)] BYTE    const,
  [out]                      ULONG   *pcbData
);

Parameters

tkObj [in]: A metadata token representing the object that owns the custom attribute.
szName [in]: The name of the custom attribute.
const [out]: A pointer to an array of data that is the value of the custom attribute.
pcbData [out]: The size in bytes of the data returned in const.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

It is legal to define multiple custom attributes for the same owner; they may even have the same name. However, GetCustomAttributeByName returns only one instance. (GetCustomAttributeByName returns the first instance that it encounters.) To find all instances of a custom attribute, call the EnumCustomAttributes method.
