SqlConnectionStringBuilder.MultipleActiveResultSets 属性

定义

命名空间:
System.Data.SqlClient
程序集:
System.Data.dll

如果为 true，应用程序可以维护多个活动结果集（MARS）。 如果为 false，应用程序必须处理或取消一个批处理中的所有结果集，然后才能在该连接上执行任何其他批处理。

有关详细信息，请参阅多个活动结果集（MARS）。

public:
 property bool MultipleActiveResultSets { bool get(); void set(bool value); };
public bool MultipleActiveResultSets { get; set; }
member this.MultipleActiveResultSets : bool with get, set
Public Property MultipleActiveResultSets As Boolean

属性值

Boolean

属性的值 MultipleActiveResultSets ，或者 false 未提供任何值。

示例

以下示例显式启用“多个活动结果集”功能。

using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder();
        builder.DataSource = "(local)";
        builder.IntegratedSecurity = true;
        builder.InitialCatalog = "AdventureWorks";

        // The connection does not allow multiple active result sets
        // by default, so this line of code explicitly
        // enables this feature. Note that this feature is
        // only available when programming against SQL Server 2005
        // or later.
        builder.MultipleActiveResultSets = true;

        Console.WriteLine(builder.ConnectionString);
        Console.WriteLine();

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

Imports System.Data.SqlClient
Module Module1
    Sub Main()
        Dim builder As New SqlConnectionStringBuilder
        builder.DataSource = "(local)"
        builder.IntegratedSecurity = True
        builder.InitialCatalog = "AdventureWorks"

        ' The connection does not allow multiple active result sets
        ' by default, so this line of code explicitly
        ' enables this feature. Note that this feature is 
        ' only available when programming against SQL Server 2005
        ' or later.
        builder.MultipleActiveResultSets = True

        Console.WriteLine(builder.ConnectionString)
        Console.WriteLine()

        Console.WriteLine("Press Enter to continue.")
        Console.ReadLine()
    End Sub
End Module
