Remarks

GetExpression evaluates an expression based on the current stack frame. If the expression can be parsed but not evaluated, an object is returned but will not contain a valid value.

Examples

The following example shows how to use the GetExpression method.

Sub DisplayExpression(Optional ByVal str As String = "")
    Dim expr As Expression
    expr = DTE2.Debugger.GetExpression(str)

    If (expr.IsValidValue) Then
        MsgBox(expr.Name + " = " + expr.Value)
    Else
        MsgBox("Expression was not valid")
    End If
End Sub
