  • Article

Gets common language runtime (CLR) version information associated with a given ICLRRuntimeInfo interface.

This method supersedes the following functions:

Syntax

HRESULT GetVersionString(  
    [out, size_is(*pcchBuffer)] LPWSTR pwzBuffer,  
    [in, out]  DWORD *pcchBuffer);

Parameters

pwzBuffer
[out] The .NET Framework compilation version in the format "vA.B[.X]". A, B, and X are decimal numbers that correspond to the major version, the minor version, and the build number. X is optional. If X is not present, there is no trailing period.

Note

This parameter must match the directory name for the .NET Framework version, as it appears under C:\Windows\Microsoft.NET\Framework.

Example values are "v1.0.3705", "v1.1.4322", "v2.0.50727", and "v4.0.x", where x depends on the build number installed. Note that the "v" prefix is mandatory.

pchBuffer
[in, out] Specifies the size of pwzBuffer to avoid buffer overruns. If pwzBuffer is null, pchBuffer returns the required size of pwzBuffer to allow preallocation.

Return Value

This method returns the following specific HRESULTs as well as HRESULT errors that indicate method failure.
