Assembly: mscorlib (in mscorlib.dll)
'Declaration Public Overrides Function ToString As String 'Usage Dim instance As Exception Dim returnValue As String returnValue = instance.ToString()
Implements
_Exception.ToStringToString returns a representation of the current exception that is intended to be understood by humans. Where the exception contains culture-sensitive data, the string representation returned by ToString is required to take into account the current system culture. Although there are no exact requirements for the format of the returned string, it should attempt to reflect the value of the object as perceived by the user.
The default implementation of ToString obtains the name of the class that threw the current exception, the message, the result of calling ToString on the inner exception, and the result of calling Environment.StackTrace. If any of these members is Nothing, its value is not included in the returned string.
If there is no error message or if it is an empty string (""), then no error message is returned. The name of the inner exception and the stack trace are returned only if they are not Nothing.
This method overrides Object.ToString.
The following example causes an exception and displays the result of calling ToString on that exception.
Imports System Public Class [MyClass] End Class '[MyClass] Public Class ArgExceptionExample Public Shared Sub Main() Dim my As New [MyClass]() Dim s As String = "sometext" Try Dim i As Integer = s.CompareTo(my) Catch e As Exception Console.WriteLine("Error: {0}", e.ToString()) End Try End Sub 'Main End Class 'ArgExceptionExample
This code has the following output:
Error: System.ArgumentException: Object must be of type String. at System.String.CompareTo(Object value) at ArgExceptionExample.Main()
