如何：將使用者資訊指派給群組連接How to: Assign User Information to Group Connections

下列範例示範如何將使用者資訊指派給群組連線，並假設應用程式會在呼叫這段程式碼之前設定 UserName、SecurelyStoredPassword 和 Domain 變數，且 UserName 為唯一。The following example demonstrates how to assign user information to group connections, assuming that the application sets the variables UserName, SecurelyStoredPassword, and Domain before this section of code is called and that UserName is unique.

將使用者資訊指派給群組連線To assign user information to a group connection

  1. 建立連線群組名稱。Create a connection group name.

    SHA1Managed Sha1 = new SHA1Managed();  
Byte[] updHash = Sha1.ComputeHash(Encoding.UTF8.GetBytes(UserName + SecurelyStoredPassword + Domain));  
String secureGroupName = Encoding.Default.GetString(updHash);  

    Dim Sha1 As New SHA1Managed()  
Dim updHash As [Byte]() = Sha1.ComputeHash(Encoding.UTF8.GetBytes((UserName + SecurelyStoredPassword + Domain)))  
Dim secureGroupName As [String] = Encoding.Default.GetString(updHash)

  2. 建立特定 URL 的要求。Create a request for a specific URL. 例如，下列程式碼會建立 URL http://www.contoso.com. 的要求For example, the following code creates a request for the URL http://www.contoso.com.

    WebRequest myWebRequest=WebRequest.Create("http://www.contoso.com");  

    Dim myWebRequest As WebRequest = WebRequest.Create("http://www.contoso.com")

  3. 設定 Web 要求的認證和連線群組名稱，並呼叫 GetResponse 來擷取 WebResponse 物件。Set the credentials and Connection GroupName for the Web request, and call GetResponse to retrieve a WebResponse object.

    myWebRequest.Credentials = new NetworkCredential(UserName, SecurelyStoredPassword, Domain);
myWebRequest.ConnectionGroupName = secureGroupName;  

WebResponse myWebResponse=myWebRequest.GetResponse();  

    myWebRequest.Credentials = New NetworkCredential(UserName, SecurelyStoredPassword, Domain)  
myWebRequest.ConnectionGroupName = secureGroupName  

Dim myWebResponse As WebResponse = myWebRequest.GetResponse()

  4. 使用 WebRespose 物件之後，關閉回應資料流。Close the response stream after using the WebRespose object.

    MyWebResponse.Close();  

    MyWebResponse.Close()

範例Example

// Create a connection group name.  
SHA1Managed Sha1 = new SHA1Managed();  
Byte[] updHash = Sha1.ComputeHash(Encoding.UTF8.GetBytes(UserName + SecurelyStoredPassword + Domain));  
String secureGroupName = Encoding.Default.GetString(updHash);  
  
// Create a request for a specific URL.  
WebRequest myWebRequest=WebRequest.Create("http://www.contoso.com");  
  
myWebRequest.Credentials = new NetworkCredential(UserName, SecurelyStoredPassword, Domain);
myWebRequest.ConnectionGroupName = secureGroupName;  
  
WebResponse myWebResponse=myWebRequest.GetResponse();  
  
// Insert the code that uses myWebResponse.  
  
MyWebResponse.Close();  

' Create a secure group name.  
Dim Sha1 As New SHA1Managed()  
Dim updHash As [Byte]() = Sha1.ComputeHash(Encoding.UTF8.GetBytes((UserName + SecurelyStoredPassword + Domain)))  
Dim secureGroupName As [String] = Encoding.Default.GetString(updHash)  
  
' Create a request for a specific URL.  
Dim myWebRequest As WebRequest = WebRequest.Create("http://www.contoso.com")  
  
myWebRequest.Credentials = New NetworkCredential(UserName, SecurelyStoredPassword, Domain)  
myWebRequest.ConnectionGroupName = secureGroupName  
  
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()  
  
' Insert the code that uses myWebResponse.  
MyWebResponse.Close()
