SqlConnectionStringBuilder.MultipleActiveResultSets 属性

定义

如果为 true,则应用程序可以维护多个活动结果集 (MARS)。 如果为 false,则应用程序必须先处理或取消某一批中的所有结果集,才可以在该连接上执行任何其他批次。 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

MultipleActiveResultSets 属性的值,或者,如果未提供任何值,则为 false

示例

以下示例显式启用多个活动结果集功能。

using Microsoft.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();
    }
}

注解

此属性对应于连接字符串中的“多个活动结果集”键。
