获取或设置说明文本，该文本会显示在用户在其中选择提供者将连接到的使用者连接点的那部分连接用户界面 (UI) 中。

public:
 virtual property System::String ^ ConnectToConsumerInstructionText { System::String ^ get(); void set(System::String ^ value); };

public virtual string ConnectToConsumerInstructionText { get; set; }

member this.ConnectToConsumerInstructionText : string with get, set

Public Overridable Property ConnectToConsumerInstructionText As String

属性值

String

一个字符串，包含关于创建到提供者的使用者连接的说明。默认文本是一个由 .NET Framework 提供的、特定于区域性的字符串。

示例

下面的代码示例演示如何将 ConnectToConsumerInstructionText 属性与控件一起使用 ConnectionsZone 。该示例仅包含演示如何使用该属性的网页的代码;有关运行示例所需的其他两个代码文件，请参阅类概述的 ConnectionsZone “示例”部分。代码示例有四个部分：

允许用户在网页上切换显示模式的用户控件。从 ConnectionsZone 类概述中获取此代码。
包含邮政编码接口的代码的源文件，以及充当连接提供程序和使用者的两 WebPart 个控件。从 ConnectionsZone 类概述中获取此代码。
承载所有控件的网页，声明一个 <asp:connectionszone> 元素，并演示如何以编程方式使用该属性。
说明示例在浏览器中的工作原理。

网页声明一个 <asp:connectionszone> 元素，在方法中 Page_PreRender ，代码将值分配给 ConnectToConsumerInstructionText 属性。

在浏览器中加载页面。使用 显示模式 控件切换到连接模式。单击 邮政编码提供程序 控件上的谓词菜单箭头，然后单击连接谓词。单击“ 结束连接 ”按钮以结束连接，然后单击 提供程序的“选择使用者”以使用超链接进行连接 。此时会显示使用者连接 UI，分配给该属性的 ConnectToConsumerInstructionText 自定义文本显示在控件上方，该控件允许你选择使用者上的连接点以与提供程序连接。

注解

该 ConnectToConsumerInstructionText 属性在特定连接方案中生效。当用户单击提供程序控件上的连接谓词时，该 ConnectionsZone 控件会显示一部分连接 UI，使用户能够选择使用者。如果用户在使用者上单击了连接谓词，则连接 UI 将执行反向操作，并显示有关连接到提供程序的信息。

属性中的 ConnectToConsumerInstructionText 文本显示在下拉列表控件的正上方，这些控件包含提供程序可以连接到的可用使用者连接点。

可以通过在页面元素的<asp:connectionszone>开始标记中使用属性以声明方式ConnectToConsumerInstructionText设置此属性，也可以以编程方式设置该属性。
