範例

以下範例取一個參數，判斷該路徑是否對應一個有效的 DirectoryEntry。

Dim myADSPath As String = "LDAP://onecity/CN=Users,DC=onecity,DC=corp,DC=fabrikam,DC=com"
' Determine whether the given path is correct for the DirectoryEntry.
If DirectoryEntry.Exists(myADSPath) Then
   Console.WriteLine("The path {0} is valid",myADSPath)
Else
   Console.WriteLine("The path {0} is invalid",myADSPath)
End If

string myADSPath ="LDAP://onecity/CN=Users,DC=onecity,DC=corp,DC=fabrikam,DC=com";

// Determine whether the given path is correct for the DirectoryEntry.
if (DirectoryEntry.Exists(myADSPath))
{
    Console.WriteLine("The path {0} is valid",myADSPath);
}
    else
{
    Console.WriteLine("The path {0} is invalid",myADSPath);
}
