SqlConnectionStringBuilder.Keys 屬性

定義

命名空間:

System.Data.SqlClient

組件:

System.Data.dll

取得 ICollection 中包含索引鍵的 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

屬性值

ICollection

ICollection 中包含索引鍵的 SqlConnectionStringBuilder。

範例

下列主控台應用程式範例會建立新的 SqlConnectionStringBuilder。 此程式碼會針對 ICollection 屬性傳回的 Keys 執行迴圈，以顯示索引鍵/值組。

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

備註

雖然 ICollection 中值的順序並未指定，但此順序會與 ICollection 屬性傳回之 Values 中關聯值的順序相同。
