The Exception to convert to an HRESULT.
Return ValueThe HRESULT mapped to the supplied exception.
GetHRForException also sets up an IErrorInfo interface for the exception that can be obtained by calling the GetErrorInfo COM API method. You can use this method to return an HRESULT value on a managed class implemention of a COM interface where you apply the System.Runtime.InteropServices.PreserveSigAttribute. Have the attributed method catch all exceptions and use GetHRForException to return the appropriate HRESULT value. Allowing an exception to propagate outside the method produces incorrect behavior. (In fact, the common language runtime fails to pass an exception to a COM client calling such a method through a v-table.) For additional information about the IErrorInfo interface and GetErrorInfo COM methods, see the MSDN Library.
Note that the GetHRForException method sets the IErrorInfo of the current thread. This can cause unexpected results for methods like the ThrowExceptionForHR methods that default to using the IErrorInfo of the current thread if it is set.
