OracleConnectionStringBuilder.DataSource 属性

定义

命名空间:

System.Data.OracleClient

程序集:

System.Data.OracleClient.dll

获取或设置要连接到的 Oracle 数据源的名称。

public:
 property System::String ^ DataSource { System::String ^ get(); void set(System::String ^ value); };

public string DataSource { get; set; }

member this.DataSource : string with get, set

Public Property DataSource As String

属性值

String

为 DataSource 属性的值，或者，如果未提供任何值，则为 Empty。

示例

以下示例演示 OracleConnectionStringBuilder 类将“数据源”的同义词连接字符串键转换为已知键。

// You may need to set a reference to the System.Data.OracleClient
// assembly before you can run this sample.
using System.Data.OracleClient;

class Program
{
    static void Main()
    {
        OracleConnectionStringBuilder builder =
            new OracleConnectionStringBuilder(
            "Server=OracleDemo;Integrated Security=True");

        // Display the connection string, which should now
        // contains the "Data Source" key, as opposed to the
        // supplied "Server".
        Console.WriteLine(builder.ConnectionString);

        // Retrieve the DataSource property.
        Console.WriteLine("DataSource = " + builder.DataSource);

        Console.WriteLine("Press any key to continue.");
        Console.ReadLine();
    }
}

' You may need to set a reference to the System.Data.OracleClient
' assembly before running this example.
Imports System.Data.OracleClient

Module Module1

  Sub Main()
    Dim builder As _
     New OracleConnectionStringBuilder( _
     "Server=OracleDemo;Integrated Security=True")

    ' Display the connection string, which should now 
    ' contains the "Data Source" key, as opposed to the 
    ' supplied "Server".
    Console.WriteLine(builder.ConnectionString)

    ' Retrieve the DataSource property.
    Console.WriteLine("DataSource = " & builder.DataSource)

    Console.WriteLine("Press any key to continue.")
    Console.ReadLine()
  End Sub

End Module

注解

此属性对应于连接字符串中的“数据源”和“服务器”键。 无论在提供的连接字符串中提供了这些值中的哪一个，由 OracleConnectionStringBuilder 创建的连接字符串都将使用已知的“数据源”键。 如果在您尝试设置此属性时传入的值为 null，则将重置 DataSource 属性。 如果尚未设置该值，并且开发人员尝试检索属性，则返回值为 Empty。
