获取包含 ICollection 中的键的 SqlConnectionStringBuilder。

 virtual property System::Collections::ICollection ^ Keys { System::Collections::ICollection ^ get(); };
public override System.Collections.ICollection Keys { get; }
member this.Keys : System.Collections.ICollection
Public Overrides ReadOnly Property Keys As ICollection

属性值

ICollection

一个 ICollection，它包含 SqlConnectionStringBuilder 中的键。

示例

以下控制台应用程序示例新建一个 SqlConnectionStringBuilder。 该代码循环访问显示键/值对的 ICollection 属性返回的 Keys。

using System.Data.SqlClient;

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

        // Loop through the collection of keys, displaying
        // the key and value for each item:
        foreach (string key in builder.Keys)
            Console.WriteLine("{0}={1}", key, builder[key]);

        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"

        ' Loop through the collection of keys, displaying 
        ' the key and value for each item.
        For Each key As String In builder.Keys
            Console.WriteLine("{0}={1}", key, builder(key))
        Next

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

注解

ICollection 中的值的顺序未指定，但与 ICollection 属性返回的 Values 中的关联值顺序相同。
