ASP.NET in a Nutshell

Name

AllErrors

Synopsis

ExceptionArray = Context.AllErrors

Returns an array of Exception objects representing all accumulated errors that occurred in the current request.

As in classic ASP, the Server.GetLastError method returns an ASPError object. This mechanism is still available, though the returned value is now of type Exception rather than ASPError.

Parameters

None

Example

The example checks to see if the AllErrors array contains any elements and if so, displays them:

Sub Page_Load(  )
    Dim i as Integer
    Dim e As New Exception("A generalized error.")
    Context.AddError(e)
    If Not Context.AllErrors Is Nothing Then
        For i = 0 to Context.AllErrors.Length - 1 
            Message.Text = Message.Text & _ 
                "Exception: " & _
                Context.AllErrors(i).ToString(  ) & "<br/>"
        Next
    Else
        Message.Text = "No Errors to report."
    End if
End Sub

Notes

Unlike classic ASP, arrays in ASP.NET are zero-based, so the first element in any collection or array will be 0, not 1. Thus, in the example above, the array is indexed from 0 to Length - 1, not from 1 to Length.
