Property Value Type: System.StringThe error message that explains the reason for the exception, or an empty string ("").Implements_Exception.MessageRemarksError messages target the developer who is handling the exception. The text of the Message property should completely describe the error and, when possible, should also explain how to correct the error. Top-level exception handlers may display the message to end-users, so you should ensure that it is grammatically correct and that each sentence of the message ends with a period. Do not use question marks or exclamation points. If your application uses localized exception messages, you should ensure that they are accurately translated. Security Note Do not disclose sensitive information in exception messages without checking for the appropriate permissions. The value of the Message property is included in the information returned by ToString.The Message property is set only when creating an Exception. If no message was supplied to the constructor for the current instance, the system supplies a default message that is formatted using the current system culture.Windows Runtime and .NET Framework 4.5.1Starting with the .NET Framework 4.5.1 and Windows 8.1, the fidelity of error messages from exceptions that are propagated from Windows R

Displaying Message Boxes Visual Studio .NET 2003 A MessageBox is a predefined dialog box that displays application-related information to the user. Message boxes are also used to request information from the user. To display information to the user in a message box Navigate to where you would like to add the code for the message box. Add code using the MessageBox.Show method. The following code demonstrates how to call the Show method of the MessageBox class to display information to the user. The call to the Show method uses the optional style parameter to specify the type of icon to display in the message box that best fits the type of message box being displayed: Copy ' Visual Basic Public Sub PerformCalculations() ' Code is entered here that performs a calculation. ' Display a message box informing the user that the calculations ' are complete. MessageBox.Show("The calculations are complete", "My Application", _ MessageBoxButtons.OKCancel, MessageBoxIcon.Asterisk) End Sub
our C# NET eBook Try ... Catch in C# .NET << Continues from the previous lesson C# has some inbuilt objects you can use to deal with http://www.homeandlearn.co.uk/csharp/csharp_s5p6.html any potential errors in your code. You tell C# to Try some code, and if can't do anything with it you can Catch the errors. Here's the syntax: try { } catch { } In http://www.c-sharpcorner.com/forums/how-to-get-error-message-from-procedure-into-display-on-c-sharp the code below, we're trying to load a text file into a RichTextBox called rtb: try { rtb.LoadFile("C:\\test.txt"); } catch (System.Exception excep) { MessageBox.Show(excep.Message); } First, note the extra backslash after C: C:\\test.txt The extra error message backslash is called an escape character. You need to escape a single backslash because C# doesn’t like you typing just one of them. The code we want to execute goes between the curly brackets of try. We know that files go missing, however, and want to trap this "File not Found" error. We can do that in the catch part. Note what goes between the round brackets after catch: System.Exception excep error message c# Exception is the inbuilt object that handles errors, and this follows the word System (known as a namespace). After System.Exception, you type a space. After the space, you need the name of a variable (excep is just a variable name we made up and, like all variable names, you call it just about anything you like). The code between the curly brackets of catch is this: MessageBox.Show(excep.Message); So we're using a message box to display the error. After the variable name (excep for us), type a dot and you'll see the IntelliSense list appear: If you just want to display the inbuilt system message, select Message from the list. When the programme is run, you'll see a message box like this: If you know the type of error that will be generated, you can use that instead: catch (System.IO.FileNotFoundException) { MessageBox.Show("File not found"); } To find out what type of error will be generated, use this: catch (System.Exception excep) { MessageBox.Show( excep.GetType().ToString() ); } The message box will tell you what system error is being generated. You can then use this between the round brackets of catch. If you want to keep things really simple, though, you can miss out the round brackets after catch. In the code below,
