Namespace:  EnvDTE
Assembly:  EnvDTE (in EnvDTE.dll)

Syntax

'Declaration
Function GetExpression ( _
    ExpressionText As String, _
    UseAutoExpandRules As Boolean, _
    Timeout As Integer _
) As Expression
Expression GetExpression(

    [InAttribute] String^ ExpressionText, 
    [InAttribute] bool UseAutoExpandRules, 
    [InAttribute] int Timeout

        ExpressionText:string * 
        UseAutoExpandRules:bool * 
        Timeout:int -> Expression
function GetExpression(
    ExpressionText : String, 
    UseAutoExpandRules : boolean, 
    Timeout : int
) : Expression

Parameters

  • ExpressionText
    Type: System.String

    The expression text to be evaluated.

  • UseAutoExpandRules
    Type: System.Boolean

    true if the auto expand rules should be used; otherwise, false.

  • Timeout
    Type: System.Int32

    The timeout period, in milliseconds.

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 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

End Sub
