以指定的名稱傳回或設定變數。

命名空間： EnvDTE
組件： EnvDTE (在 EnvDTE.dll 中)

語法

'宣告
Default Property VariableValue ( _
    VariableName As String _
) As Object
    Get
    Set

Object this[
    string VariableName
] { get; set; }

property Object^ default[String^ VariableName] {
    Object^ get (String^ VariableName);
    void set (String^ VariableName, Object^ value);
}

abstract VariableValue : Object with get, set

JScript 不支援索引屬性。

參數

VariableName
型別：System.String
必要項。代表要擷取的變數名稱的字串。

屬性值

型別：System.Object
代表變數的物件。

備註

如果您嘗試擷取一個不存在的變數，就會以空白值建立這個變數。如果您嘗試設定一個不存在的變數，就會以指定的值建立它。

注意事項
VariableValue 名稱字串不能含有空格、冒號 (:) 或句號 (.) 等字元。如果名稱具有上列任何一個字元，您會收到下列錯誤訊息：「值未落在預期的範圍內」。

範例

Sub OnAddinLoaded(ByVal dte As DTE)
    ' Count the number of times an add-in is loaded
    ' and store the value in the solution.
    Dim globals As Globals
    globals = dte.Solution.Globals
    If globals.VariableExists("AddinLoadCounter") Then
        ' The counter has already been set, so increment it.
        Dim int32 As System.Int32
        int32 = System.Int32.Parse(CStr(globals("AddinLoadCounter")))
        int32 += 1
        globals("AddinLoadCounter") = int32.ToString()
    Else
        ' Counter has never been set, so create and initialize it.
        globals("AddinLoadCounter") = 1.ToString()
        globals.VariablePersists("AddinLoadCounter") = True
    End If
    MsgBox("This add-in has been loaded: " & _
    globals.VariableValue("AddinLoadCounter") & " times.")
End Sub

    }
    else

        globals["AddinLoadCounter"] = 1.ToString();
        globals.set_VariablePersists("AddinLoadCounter", true);
    }
    System.Windows.Forms.MessageBox.Show("This add-in has been loaded:
