Marshal.GetExceptionForHR Method (Int32, IntPtr)
Converts the specified HRESULT error code to a corresponding Exception object, with additional error information passed in an IErrorInfo interface for the exception object.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- errorCode
- Type: System.Int32
The HRESULT to be converted.
- errorInfo
- Type: System.IntPtr
A pointer to the IErrorInfo interface that provides more information about the error. You can specify IntPtr(0) to use the current IErrorInfo interface, or IntPtr(-1) to ignore the current IErrorInfo interface and construct the exception just from the error code.
Return Value
Type: System.ExceptionAn object that represents the converted HRESULT and information obtained from errorInfo.
Use the GetExceptionForHR method to get an Exception based on an HRESULT without having to call the ThrowExceptionForHR method and catch the exception (thus avoiding the corresponding performance overhead). The errorInfo parameter supplies additional information about the error, such as its textual description and the globally unique identifier (GUID) for the interface that defined the error.
Use this method overload if you have custom error information that you have to supply in the conversion.
