'Declaration
Function GetExpression ( _
ExpressionText As String, _
UseAutoExpandRules As Boolean, _

) As Expression
'Usage
Dim instance As Debugger
Dim ExpressionText As String
Dim UseAutoExpandRules As Boolean
Dim Timeout As Integer
Dim returnValue As Expression
returnValue = instance.GetExpression(ExpressionText, _

function GetExpression(
ExpressionText : String,
UseAutoExpandRules : boolean,
Timeout : int
) : Expression
Parameters
ExpressionText
Type: System.StringThe expression text to be evaluated.
UseAutoExpandRules

Examples
The following example demonstrates how to use M:EnvDTE.Debugger.GetExpression(System.String,System.Boolean,System.Int32) property.
Sub DisplayExpression(Optional ByVal str As String = "")
Dim expr As Expression
expr = DTE.Debugger.GetExpression(str)
If (expr.IsValidValue) Then
MsgBox(expr.Name + " = " + expr.Value)
Else
MsgBox("Expression was not valid")
End If
