Initializes a new instance of COMException with a specified message and the exception that is the root cause of this exception.
[Visual Basic] Overloads Public Sub New( _ ByVal message As String, _ ByVal inner As Exception _ ) [C#] public COMException( string message, Exception inner ); [C++] public: COMException( String* message, Exception* inner ); [JScript] public function COMException( message : String, inner : Exception );
When handling an exception, it is sometimes helpful to have a reference to the exception(s) that caused the error to occur. You can use this constructor to create a chain of new and more meaningful exceptions with the InnerException property set to the inner exception reference. This more meaningful exception can then be thrown to the caller. Note that with this functionality it is possible to create a series of linked exceptions that terminates with the exception that was first thrown. (See Exception for more information.)
COMException inherits from the Exception class. This constructor sets the properties of the Exception object as follows:
Property | Value |
---|---|
InnerException | inner. |
Message | message. |
COMException Class | COMException Members | System.Runtime.InteropServices Namespace | COMException Constructor Overload List
