定义

命名空间:
System.Data.SqlClient
程序集:
System.Data.SqlClient.dll
程序集:
System.Data.dll
包:
System.Data.SqlClient v4.8.6

获取一个包含 ICollection 中的值的 SqlConnectionStringBuilder。

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

属性值

ICollection

一个 ICollection，包含 SqlConnectionStringBuilder 中的值。

示例

以下示例首先新建一个 SqlConnectionStringBuilder，然后循环访问该对象内的所有值。

using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        SqlConnectionStringBuilder builder =
            new SqlConnectionStringBuilder(GetConnectionString());

        // Loop through each of the values, displaying the contents.
        foreach (object value in builder.Values)
            Console.WriteLine(value);

        Console.WriteLine("Press any key to continue.");
        Console.ReadLine();
    }

    private static string GetConnectionString()
    {
        // To avoid storing the connection string in your code,
        // you can retrieve it from a configuration file.
        return "Data Source=(local);Integrated Security=SSPI;" +
            "Initial Catalog=AdventureWorks; Asynchronous Processing=true";
    }
}

Imports System.Data.SqlClient
    
Module Module1
    Sub Main()
        Dim builder As _
         New SqlConnectionStringBuilder(GetConnectionString())

        ' Loop through each of the values, displaying the contents.
        For Each value As Object In builder.Values
            Console.WriteLine(value)
        Next

        Console.WriteLine("Press any key to continue.")
        Console.ReadLine()
    End Sub

    Private Function GetConnectionString() As String
        ' To avoid storing the connection string in your code,
        ' you can retrieve it from a configuration file. 
        Return "Data Source=(local);Integrated Security=SSPI;" & _
          "Initial Catalog=AdventureWorks; Asynchronous Processing=True"
    End Function
End Module

注解

ICollection 中的值的顺序未指定，但与 ICollection 属性返回的 Keys 中的关联键顺序相同。 因为每个 SqlConnectionStringBuilder 实例始终包含相同的固定键集合，所以 Values 属性始终返回与固定键集合相对应的值，顺序与键相同。
