DiscoveryClientProtocol.ReadAll(String) 方法

定义

命名空间:

System.Web.Services.Discovery

程序集:

System.Web.Services.dll

读入包含已保存的发现文档的映射的文件，并使用该文件中引用的发现文档、XML 架构定义 (XSD) 架构和服务说明填充 Documents 和 References 属性。

public:
 System::Web::Services::Discovery::DiscoveryClientResultCollection ^ ReadAll(System::String ^ topLevelFilename);

public System.Web.Services.Discovery.DiscoveryClientResultCollection ReadAll (string topLevelFilename);

member this.ReadAll : string -> System.Web.Services.Discovery.DiscoveryClientResultCollection

Public Function ReadAll (topLevelFilename As String) As DiscoveryClientResultCollection

参数

topLevelFilename

String

要读入的文件的名称，该文件包含已保存发现文档的映射。

返回

DiscoveryClientResultCollection

DiscoveryClientResultCollection，它包含在具有已保存发现文档的映射的文件中找到的结果。 文件格式是已序列化为 XML 的 DiscoveryClientProtocol.DiscoveryClientResultsFile 类；然而，通常只使用 WriteAll(String, String) 方法或 Disco.exe 创建该文件。

示例

下面的代码示例是一个 Web 窗体， DataGrid 它使用 ReadAll 该方法填充现有发现地图文档中的文档和引用的详细信息。

 protected void Discover_Click(object Source, EventArgs e)
 {
  // Specify the URL to read the discovery results from.
  string outputDirectory = DiscoDir.Text;

      DiscoveryClientProtocol client = new DiscoveryClientProtocol();
  // Use default credentials to access the files containing the discovery results.
      client.Credentials = CredentialCache.DefaultCredentials;

      try {
        DiscoveryDocument doc;
    // Read in existing discovery results.
        DiscoveryClientResultCollection results = client.ReadAll(Path.Combine(DiscoDir.Text,"results.discomap"));
      }
      catch ( Exception e2) 
      {
        DiscoveryResultsGrid.Columns.Clear();
        Status.Text = e2.Message;
      }
  // If discovery documents existed in the supplied folder, display the results in a data grid.
      if (client.Documents.Count > 0)
      PopulateGrid(client);
}

Public Sub Discover_Click(Source As Object, e as EventArgs )
   ' Specify the URL to read the discovery results from.
   Dim outputDirectory As String = DiscoDir.Text

   Dim client as DiscoveryClientProtocol = new DiscoveryClientProtocol()
   ' Use default credentials to access files containing the previously saved discovery results.
   client.Credentials = CredentialCache.DefaultCredentials
   Try 
     Dim doc As DiscoveryDocument
  
    ' Read in existing discovery results.
     Dim results As DiscoveryClientResultCollection 
     results = client.ReadAll(Path.Combine(DiscoDir.Text,"results.discomap"))

   Catch e2 As Exception
       DiscoveryResultsGrid.Columns.Clear()
       Status.Text = e2.Message
   End Try

   ' If disocvery documents existed in the supplied folder, display the results in a data grid.
    If (client.Documents.Count > 0) Then
         ' Populate the data grid with the discovery results.
     PopulateGrid(client)
    End If
End Sub

注解

方法或Disco.exe可以创建 WriteAll 包含已保存发现文档映射的文件。

如果当前目录中不存在文件，该 topLevelFilename 参数必须包含完全限定的路径。
