VSProject2.Imports 属性

项目
05/17/2015

获取与项目关联的 Imports 对象。对于 C# 项目，将 Imports 属性设置为 Nothing（nullnull 引用（在 Visual Basic 中为 Nothing）引用）。

命名空间： VSLangProj80
程序集： VSLangProj80（在 VSLangProj80.dll 中）

语法

声明
ReadOnly Property Imports As Imports

Imports Imports { get; }

property Imports^ Imports {
    Imports^ get ();
}

abstract Imports : Imports with get

function get Imports () : Imports

属性值

类型：Imports
一个 Imports 集合，其中每项表示一个导入语句。

备注

C# 项目没有项目导入。对于 C# 项目，Imports 的值为 Nothing（nullnull 引用（在 Visual Basic 中为 Nothing）引用）。

示例

若要将此示例作为外接程序运行，请参见如何：编译和运行自动化对象模型代码示例。在运行此示例之前，请打开一个 Visual Basic 项目。
