示例

本主题提供了包含源代码的 Visual Studio 网站项目:下载A Visual Studio Web site project with source code is available to accompany this topic: Download.

下面的代码示例演示如何使用TextBox控件获取用户输入。The following code example demonstrates how to use the TextBox control to get user input. 当用户单击 "添加" 按钮时,将显示在文本框中输入的值的总和。When the user clicks the Add button, the sum of the values entered in the text boxes is displayed.

重要

此示例具有一个接受用户输入的文本框,这是一个潜在的安全威胁。This example has a text box that accepts user input, which is a potential security threat. 默认情况下,ASP.NET 网页验证用户输入是否不包含脚本或 HTML 元素。By default, ASP.NET Web pages validate that user input does not include script or HTML elements. 有关详细信息,请参阅脚本侵入概述For more information, see Script Exploits Overview.

介绍Introduction

TextBox服务器控件是允许用户输入文本的输入控件。The TextBox server control is an input control that lets the user enter text. 默认情况下, TextMode控件的属性设置为TextBoxMode.SingleLine,这将显示单行文本框。By default, the TextMode property of the control is set to TextBoxMode.SingleLine, which displays a single-line text box. 但是, TextBox还可以使用控件显示多行文本框或文本框,以通过将TextMode属性的值更改为TextBoxMode.MultiLineTextBoxMode.Password,来屏蔽用户输入。However, you can also use the TextBox control to display a multiline text box or a text box that masks user input by changing the value of the TextMode property to TextBoxMode.MultiLine or TextBoxMode.Password, respectively. 使用属性指定或确定TextBox控件中显示的文本。TextThe text displayed in the TextBox control is specified or determined by using the Text property.

TextBox控件包含若干属性,使您可以控制控件的外观。The TextBox control contains several properties that allow you to control the appearance of the control. 文本框的显示宽度(以字符为字符)由其Columns属性确定。The display width of the text box, in characters, is determined by its Columns property. 如果控件是多行文本框,则显示的行数由Rows属性确定。 TextBoxIf the TextBox control is a multiline text box, the number of rows it displays is determined by the Rows property. 若要显示在TextBox控件内换行的文本,请Wraptrue属性设置为。To display text that wraps within the TextBox control, set the Wrap property to true.

通过设置几个属性,还可以指定如何TextBox在控件中输入数据。You can also specify how data is entered in the TextBox control by setting a few properties. 若要防止修改控件中显示的文本,请将ReadOnly属性设置为。 trueTo prevent the text displayed in the control from being modified, set the ReadOnly property to true. 如果要将用户输入限制为指定数量的字符,请设置MaxLength属性。If you want to limit the user input to a specified number of characters, set the MaxLength property.

有关实例TextBox的初始属性值的列表, TextBox请参见构造函数。For a list of initial property values for an instance of TextBox, see the TextBox constructor.

注意

此控件可用于接受用户输入,其中可能包括恶意客户端脚本。This control can be used to accept user input, which might include malicious client script. 在应用程序中显示可执行脚本、SQL 语句或其他代码之前,请检查从该客户端发送的任何信息。Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. 您可以使用验证控件在显示控件中的输入文本之前验证用户输入。You can use validation controls to verify user input before displaying the input text in a control. ASP.NET 提供输入请求验证功能来阻止用户输入中的脚本和 HTML。ASP.NET provides an input request validation feature to block script and HTML in user input. 有关详细信息,请参阅保护标准控件如何:通过将 HTML 编码应用到字符串,并在 ASP.NET 网页中验证用户输入来防范 Web 应用程序中的脚本攻击。For more information, see Securing Standard Controls, How to: Protect Against Script Exploits in a Web Application by Applying HTML Encoding to Strings, and Validating User Input in ASP.NET Web Pages.
