DirectorySearcher 示例

面的代码示例说明如何搜索域中的所有用户。它包含一些基本的必需任务，例如使用 C# try-catch 或 Visual Basic .NET try-catch-finally 语句捕捉错误以及可由 DirectorySearcher 对象引发的所有错误的错误处理。

try
{
// Bind to the users container.
DirectoryEntry entry = new DirectoryEntry("LDAP://CN=users,DC=fabrikam,DC=com");
// Create a DirectorySearcher object.
DirectorySearcher mySearcher = new DirectorySearcher(entry);
// Create a SearchResultCollection object to hold a collection of SearchResults
// returned by the FindAll method.
SearchResultCollection result = mySearcher.FindAll();
// Get search results. For more information, see Getting Search Results.
// ...
// This sample uses Try...Catch to catch errors.
// Create an Exception object. For more information, see System.Exception.
}
catch (System.Runtime.InteropServices.COMException)
{
System.Runtime.InteropServices.COMException exception = new System.Runtime.InteropServices.COMException();
Console.WriteLine(exception);
}
catch (InvalidOperationException)
{
InvalidOperationException InvOpEx = new InvalidOperationException();
Console.WriteLine(InvOpEx.Message);
}
catch (NotSupportedException)
{
NotSupportedException NotSuppEx = new NotSupportedException();
Console.WriteLine(NotSuppEx.Message);
}
