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.ICollectionPublic 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 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。
