RegularExpressionValidator 類別

提供控制項功能，驗證另一個控制項的值符合所提供的規則運算式 (Regular Expression)。

public class System.Web.UI.MobileControls.RegularExpressionValidator : 
   System.Web.UI.MobileControls.BaseValidator

備註

這個類別與 ASP.NET System.Web.UI.WebControls.RegularExpressionValidator 控制項的行為相同。

依預設值，表單上的 Command 控制項會引發表單上的驗證程式控制項，在表單呈送至伺服器時執行驗證。若要停用自動驗證，請將 Command 控制項上的 CausesValidation 屬性設定為 false。

範例

下列範例顯示您如何在載入網頁時，以程式設計方式加入規則運算式屬性，例如 ValidationExpression 和 Text 屬性。
