DirectorySearcher.Asynchronous 属性

定义

获取或设置一个值,该值指示是否异步执行搜索。

public:
 property bool Asynchronous { bool get(); void set(bool value); };
public bool Asynchronous { get; set; }
[System.DirectoryServices.DSDescription("DSAsynchronous")]
[System.Runtime.InteropServices.ComVisible(false)]
public bool Asynchronous { get; set; }
member this.Asynchronous : bool with get, set
[<System.DirectoryServices.DSDescription("DSAsynchronous")>]
[<System.Runtime.InteropServices.ComVisible(false)>]
member this.Asynchronous : bool with get, set
Public Property Asynchronous As Boolean

属性值

如果异步执行搜索,则为 true;否则为 false

属性

示例

以下 C# 示例演示如何创建异步搜索。

using System.DirectoryServices;  
...  
// Bind to the users container.  
DirectoryEntry entry = new DirectoryEntry("LDAP://CN=users,DC=fabrikam,DC=com");  
// Create a DirectorySearcher object.  
DirectorySearcher src = new DirectorySearcher(entry);  
//Set the Asynchronous property to true.  
src.Asynchronous = true;  
//Use the FindAll method to get search results.  
SearchResultCollection res = src.FindAll();  

注解

异步搜索可以在找到结果时显示结果,同时搜索其他结果。 这对于填充列表框等任务非常有用。

此属性的默认设置为 false
