handling is straightforward to implement, and the same concepts are applicable to either VB.NET or C#. Throughout this section, example code will be shown in both languages. VB .NET allows backward compatibility by also providing unstructured exception handling, via the familiar On Error GoTo statement and Err object, although this model is not discussed in this section. Exceptions Exceptions are used to handle error conditions in Visual Studio .NET. They provide information about the error condition. An exception is an instance of a class which inherits from the System.Exception base class. Many different types of exception class are provided by the .NET Framework, and it is also possible to create your own exception classes. Each type extends the basic functionality of the System.Exception class by allowing further access to information about the specific type of error that has occurred. An instance of an Exception class is created and thrown when the .NET Framework encounters an error condition. You can deal with exceptions by using the Try, Catch Finally construct. Try, Catch, Finally This construct allows you to catch errors that are thrown within your code. An example of this construct is shown below. An attempt is made to rotate an envelope, which throws an error. C# try { IEnvelope env = new EnvelopeClass(); env.PutCoords(0D, 0D, 10D, 10D); ITransform2D trans = (ITransform2D) env; trans.Rotate(env.LowerLeft, 1D); } catch (System.Exception ex) { MessageBox.Show("Error: " + ex.Message); } finally { // Perform any tidy up code. } VB.NET Try Dim env As IEnvelope = New EnvelopeClass() env.PutCoords(0D, 0D, 10D, 10D) Dim trans As ITransform2D = env trans.Rotate(env.LowerLeft, 1D) Catch ex As System.Exception MessageBox.Show("Error: " + ex.Message) Finally ' Perform any tidy up code. End Try The Try block is placed around the code which may fail. If an error is thrown within the Try block, the point of execution will switch to the first Catch block. The Catch block handles a thrown error. A Catch block is executed when the Type of a thrown error matches the Type of error specified by the Catch block. You can have more than one Catch block to handle different kinds of errors. The code shown below checks first if the exception thrown is a DivideByZeroException. C# ... catch (DivideByZeroException divEx) { // Perform divide by zero error handling. } catch (System.Exception ex) { // Perform general error handling. } ... VB.NET ... Catch divEx As DivideByZeroException // Perform divide by zero error handling. Catch ex As System.Exception // Perform general error handling. ... If you do h
