ValidatorCollection ValidatorCollection ValidatorCollection ValidatorCollection Class

定義

公開 IValidator 參考的陣列。Exposes an array of IValidator references. 這個類別無法被繼承。This class cannot be inherited.

public ref class ValidatorCollection sealed : System::Collections::ICollection
public sealed class ValidatorCollection : System.Collections.ICollection
type ValidatorCollection = class
    interface ICollection
    interface IEnumerable
Public NotInheritable Class ValidatorCollection
Implements ICollection

範例

下列程式碼範例示範如何存取透過集合Page.Validators屬性,然後使用GetEnumerator來逐一查看值的方法。The following code example demonstrates how to access the collection through the Page.Validators property and use the GetEnumerator method to iterate through the values.

// Get 'Validators' of the page to myCollection.
ValidatorCollection myCollection = Page.Validators;

// Get the Enumerator.
IEnumerator myEnumerator = myCollection.GetEnumerator();
// Print the values in the ValidatorCollection.
string myStr = " ";
while ( myEnumerator.MoveNext() )
{
   myStr += myEnumerator.Current.ToString();
   myStr += " ";
}
messageLabel.Text = myStr;
' Get 'Validators' of the page to myCollection.
Dim myCollection As ValidatorCollection = Page.Validators
' Get the Enumerator.
Dim myEnumerator As IEnumerator = myCollection.GetEnumerator()
' Print the values in the ValidatorCollection.
Dim myStr As String = " "
While myEnumerator.MoveNext()
   myStr += myEnumerator.Current.ToString()
   myStr += " "
End While
messageLabel.Text = myStr

備註

每個ValidatorCollection參考包含在要求的頁面上的驗證伺服器控制項有關聯。Each ValidatorCollection reference is associated with a validation server control contained on the requested page. 這些控制項將本身新增至這個集合時Init事件的Page處理物件。These controls add themselves to this collection when the Init event of the Page object is handled. 它們自己中移除時Unload事件的Page處理物件。They remove themselves when the Unload event of the Page object is handled. Page類別會繼承這兩種方法從Control類別。The Page class inherits both of these methods from the Control class.

您可以存取這個集合,其方法和其屬性,透過Page.Validators屬性。You can access this collection, its methods, and its properties through the Page.Validators property. 如果這個集合中的任何驗證程式的測試的條件失敗時,Page.IsValid屬性設定為falseIf the tested condition of any validator in this collection fails, the Page.IsValid property is set to false.
