命名空间： EnvDTE
程序集： EnvDTE（在 EnvDTE.dll 中）

语法

声明
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 不支持索引属性。

参数

VariableName
类型：System.String
必选。表示要检索的变量名的字符串。

属性值

类型：System.Object
表示该变量的对象。

备注

如果尝试检索不存在的变量，将创建带空值的变量。如果尝试设置不存在的变量，将创建带指定值的变量。

提示

VariableValue 名称字符串不能包括空格、冒号 (:) 或句点 (.) 字符。如果名称包含任何这些字符，则会收到错误“值不在预期的范围内”。

示例

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

void OnAddinLoaded(_DTE applicationObject)
{
    // Count the number of times an add-in is loaded
    // and store the value in the solution.
    Globals globals;
    globals = applicationObject.Solution.Globals;
    if(globals.get_VariableExists("AddinLoadCounter"))
    {
        // The counter has already been set, so increment it.
        System.Int32 int32;
        int32 = System.Int32.Parse((string)
        globals["AddinLoadCounter"]);
        int32++;
        globals["AddinLoadCounter"] = int32.ToString();
    }
    else
    {
        // Counter has never been set, so create and initialize it.
        globals["AddinLoadCounter"] = 1.ToString();
        globals.set_VariablePersists("AddinLoadCounter", true);
    }
    System.Windows.Forms.MessageBox.Show("This add-in has been loaded: 
    " + globals.VariableValue["AddinLoadCounter"] + " times.");
