SqlConnectionStringBuilder.ApplicationName 属性

定义

获取或设置与连接字符串关联的应用程序的名称。

public:
 property System::String ^ ApplicationName { System::String ^ get(); void set(System::String ^ value); };
public string ApplicationName { get; set; }
member this.ApplicationName : string with get, set
Public Property ApplicationName As String

属性值

应用程序的名称;或者,如果未提供名称,则为“.NET SqlClient Data Provider”。

例外

若要将值设置为 null,请使用 Value

示例

以下示例创建一个新的 SqlConnectionStringBuilder 并在对象的构造函数中分配一个连接字符串。 该代码显示已分析并重新创建的版本的连接字符串,然后修改对象的 ApplicationName 属性。 最后,该代码显示包含新键/值对的新连接字符串。

using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        try
        {
            string connectString = "Server=(local);Initial Catalog=AdventureWorks;" +
                "Integrated Security=true";
            SqlConnectionStringBuilder builder =
                new SqlConnectionStringBuilder(connectString);
            Console.WriteLine("Original: " + builder.ConnectionString);
            Console.WriteLine("ApplicationName={0}",
                builder.ApplicationName);

            builder.ApplicationName = "My Application";
            Console.WriteLine("Modified: " + builder.ConnectionString);

            Console.WriteLine("Press any key to finish.");
            Console.ReadLine();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }
}
Imports System.Data.SqlClient

Module Module1

    Sub Main()
        Try
            Dim connectString As String = _
             "Server=(local);Initial Catalog=AdventureWorks;" & _
                 "Integrated Security=True"
            Dim builder As New SqlConnectionStringBuilder(connectString)
            Console.WriteLine("Original: " & builder.ConnectionString)
            Console.WriteLine("ApplicationName={0}", _
                builder.ApplicationName)
            builder.ApplicationName = "My Application"
            Console.WriteLine("Modified: " & builder.ConnectionString)

            Console.WriteLine("Press any key to finish.")
            Console.ReadLine()

        Catch ex As Exception
            Console.WriteLine(ex.Message)
        End Try
    End Sub
End Module

该示例在控制台窗口中显示以下文本:

Original: Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True
ApplicationName=".Net SqlClient Data Provider"
Modified: Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True;Application Name="My Application"

注解

此属性与连接字符串内的“Application Name”和“app”键相对应。
