定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
得到 ICollection 一個包含 SqlConnectionStringBuilder鍵的 。
public:
virtual property System::Collections::ICollection ^ Keys { System::Collections::ICollection ^ get(); };public override System.Collections.ICollection Keys { get; }member this.Keys : System.Collections.ICollectionPublic Overrides ReadOnly Property Keys As ICollection屬性值
一個 ICollection 包含 的鍵 SqlConnectionStringBuilder。
範例
以下主控台應用程式範例會建立一個新的 SqlConnectionStringBuilder。 程式碼會迴圈於 ICollection 顯示鍵值對的屬性所回傳 Keys 的值。
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
中ICollection值的順序未明確說明，但與屬性回傳Values的相關值ICollection順序相同。
