Marshal::GetHRForLastWin32Error Method

Returns the HRESULT corresponding to the last error incurred by Win32 code executed using Marshal.

Namespace:  System.Runtime.InteropServices
Assembly:  mscorlib (in mscorlib.dll)

public:
static int GetHRForLastWin32Error()

Return Value

Type: System::Int32
The HRESULT corresponding to the last Win32 error code.

The target function must have had the setLastError metadata flag set. For example, the SetLastError field of the System.Runtime.InteropServices::DllImportAttribute must be true. The process for setting this flag depends on the source language used: C# and C++ are false by default, but the Declare statement in Visual Basic is true.

The following example demonstrates how to retrieve an HRESULT corresponding to a Win32 error code using the GetHRForLastWin32Error method.

No code example is currently available or this language may not be supported.
