SqlConnectionStringBuilder.Keys 属性

定义

获取包含 ICollection 中的键的 SqlConnectionStringBuilder

public:
 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

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 Microsoft.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();
    }
}

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。
