[System.ComponentModel.TypeConverter(typeof(System.Data.SqlClient.SqlConnectionStringBuilder+SqlDataSourceConverter))]
public string DataSource { get; set; }
[<System.ComponentModel.TypeConverter(typeof(System.Data.SqlClient.SqlConnectionStringBuilder+SqlDataSourceConverter))>]
member this.DataSource : string with get, set
Public Property DataSource As String

属性值

TypeConverterAttribute

例外

ArgumentNullException

若要将值设置为 null，请使用 Value。

示例

以下示例演示了 SqlConnectionStringBuilder 类将“数据源”连接字符串键的同义词转换为已知键：

using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(
            "Network Address=(local);Integrated Security=SSPI;" +
            "Initial Catalog=AdventureWorks");

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

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

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

Imports System.Data.SqlClient

Module Module1

    Sub Main()
        Dim builder As _
         New SqlConnectionStringBuilder( _
         "Network Address=(local);Integrated Security=SSPI;" & _
         "Initial Catalog=AdventureWorks")

        ' Display the connection string, which should now 
        ' contain the "Data Source" key, as opposed to the 
        ' supplied "Network Address".
        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”、“服务器”、“地址”、“addr”和“网络地址”密钥。 无论在提供的连接字符串中提供了哪些值，由 SqlConnectionStringBuilder 该字符串创建的连接字符串都将使用已知的“数据源”密钥。
