示例
下面的代码示例演示如何使用 ProviderSettings。
using System;
using System.Collections;
using System.Collections.Specialized;
using System.Text;
using System.Configuration;
using System.Security.Permissions;
namespace Samples.AspNet
{
// Shows how to use the ProviderSettings.
public class UsingProviderSettings
{
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
private static void GetProviderSettings()
{
// Get the application configuration file.
System.Configuration.Configuration config =
ConfigurationManager.OpenExeConfiguration(
ConfigurationUserLevel.None);
ProtectedConfigurationSection pSection =
config.GetSection("configProtectedData")
as ProtectedConfigurationSection;
ProviderSettingsCollection providerSettings =
pSection.Providers;
foreach (ProviderSettings pSettings in
providerSettings)
{
Console.WriteLine(
"Provider settings name: {0}",
pSettings.Name);
Console.WriteLine(
"Provider settings type: {0}",
pSettings.Type);
NameValueCollection parameters =
pSettings.Parameters;
IEnumerator pEnum =
parameters.GetEnumerator();
int i = 0;
while (pEnum.MoveNext())
{
string pLength =
parameters[i].Length.ToString();
Console.WriteLine(
"Provider ssettings: {0} has {1} parameters",
pSettings.Name, pLength);
}
}
}
static void Main(string[] args)
{
GetProviderSettings();
}
}
}
Imports System.Collections

Dim pSettings As ProviderSettings
For Each pSettings In providerSettings
Console.WriteLine( _

Dim parameters _
As NameValueCollection = pSettings.Parameters
Dim pEnum _
As IEnumerator = parameters.GetEnumerator()
Dim i As Integer = 0
While pEnum.MoveNext()
Dim pLength As String = _
parameters(i).Length.ToString()

下面是上述示例使用的配置文件的摘录。
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configProtectedData>
<providers>
<clear />
<add
name="TripleDESProtectedConfigurationProvider"
type="Samples.Aspnet.TripleDESProtectedConfigurationProvider, protectedconfigurationproviderlib, Version=1.0.0.0, Culture=neutral,

</providers>
</configProtectedData>
</configuration>
注解
ASP.NET 使用提供程序来执行功能所需的特定服务。 例如，成员资格功能使用提供程序来协调数据库中成员资格数据的持久性。
在配置文件中，单个提供程序将添加到 providers 特定功能节内的元素中。
类 ProviderSettings 表示添加到配置节中的 providers 元素的特定设置组。 通常， 指令指定的 add 配置属性包括名称、类型和其他属性。
