範例

本主題提供具有原始程式碼的 Visual Studio 網站專案:下載A Visual Studio Web site project with source code is available to accompany this topic: Download.

下列程式碼範例示範如何使用TextBox控制項來取得使用者輸入。The following code example demonstrates how to use the TextBox control to get user input. 當使用者按一下 [新增] 按鈕時,就會顯示在文字方塊中輸入之值的總和。When the user clicks the Add button, the sum of the values entered in the text boxes is displayed.

重要

這個範例有一個可接受使用者輸入的文字方塊,這可能會造成安全性威脅。This example has a text box that accepts user input, which is a potential security threat. 根據預設,ASP.NET Web 網頁會驗證使用者輸入未包含指令碼或 HTML 項目。By default, ASP.NET Web pages validate that user input does not include script or HTML elements. 如需詳細資訊,請參閱 Script Exploits Overview (指令碼攻擊概觀)。For more information, see Script Exploits Overview.

簡介Introduction

TextBox伺服器控制項是一個輸入控制項,可讓使用者輸入文字。The TextBox server control is an input control that lets the user enter text. 根據預設,控制項TextMode的屬性會設定為TextBoxMode.SingleLine,這會顯示單行文字方塊。By default, the TextMode property of the control is set to TextBoxMode.SingleLine, which displays a single-line text box. 不過,您也可以TextBox使用控制項來顯示多行文字方塊,或分別將TextMode屬性的值變更為TextBoxMode.MultiLineTextBoxMode.Password,以遮罩使用者輸入的文字方塊。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. TextBox控制項中顯示的文字是Text使用屬性來指定或決定。The text displayed in the TextBox control is specified or determined by using the Text property.

TextBox控制項包含數個屬性,可讓您控制控制項的外觀。The TextBox control contains several properties that allow you to control the appearance of the control. 文字方塊的顯示寬度(以字元為單位)取決於其Columns屬性。The display width of the text box, in characters, is determined by its Columns property. 如果控制項是多行文字方塊,它所顯示的資料列數目是Rows由屬性所決定。 TextBoxIf the TextBox control is a multiline text box, the number of rows it displays is determined by the Rows property. 若要顯示在TextBox控制項中換行的文字,請Wraptrue屬性設定為。To display text that wraps within the TextBox control, set the Wrap property to true.

您也可以藉由設定幾個屬性, TextBox來指定如何在控制項中輸入資料。You can also specify how data is entered in the TextBox control by setting a few properties. 若要防止控制項中顯示的文字遭到修改,請將ReadOnly屬性設定為。 trueTo prevent the text displayed in the control from being modified, set the ReadOnly property to true. 如果您想要將使用者輸入限制為指定的字元數,請設定MaxLength屬性。If you want to limit the user input to a specified number of characters, set the MaxLength property.

如需實例的TextBox初始屬性值清單, TextBox請參閱函數。For a list of initial property values for an instance of TextBox, see the TextBox constructor.

警告

這個控制項可以用來接受使用者輸入,其中可能包含惡意的用戶端腳本。This control can be used to accept user input, which might include malicious client script. 在應用程式中顯示之前,檢查是否有任何從用戶端針對可執行檔腳本、SQL 語句或其他程式碼傳送的資訊。Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. 您可以使用驗證控制項來驗證使用者輸入,然後才在控制項中顯示輸入文字。You can use validation controls to verify user input before displaying the input text in a control. ASP.NET 提供輸入要求驗證功能,以封鎖使用者輸入中的腳本和 HTML。ASP.NET provides an input request validation feature to block script and HTML in user input. 如需詳細資訊,請參閱保護標準控制項如何:將 HTML 編碼套用至字串,並在 ASP.NET Web Pages 中驗證使用者輸入,以防止 Web 應用程式中的腳本入侵。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.
