【问题描述】：
我是新手。我正在使用SimpleMembership 生成注册和登录表。但是，我收到以下异常。
例外
“System.ArgumentException”类型的异常发生在 System.Data.dll 但未在用户代码中处理
附加信息：找不到请求的 .Net Framework 数据提供者。可能没有安装。
代码
[AllowAnonymous]
[HttpGet]
public ActionResult Register1()
{
if (!WebSecurity.Initialized)
{
//WebSecurity.InitializeDatabaseConnection("My_Entities", "Users", "Id", "UserName", autoCreateTables: true);
WebSecurity.InitializeDatabaseConnection("My_Entities", "User", "Id", "Email", autoCreateTables: true);
}
return View("Register");
}
[AllowAnonymous]
[HttpPost]
public ActionResult Register1(FormCollection form)
{
WebSecurity.CreateUserAndAccount(form["username"], form["password"], new { DisplayName = form["displayname"], Country = form["country"] });
Response.Redirect("~/account/login");
return View();
}

【问题讨论】：
-
是的，我做到了。但我不明白解决方案。如果你能详细说明一下。
-
在使用
SimpleMembershipProvider时，web.config文件中需要有正确的 SQL Server（和实体框架）连接字符串。检查相应的数据提供者是否已正确安装。 -
我在帖子中添加了我的
WEB.CONFIG文件。有人可以告诉我应该添加什么。对不起，我是新手。 -
您似乎在
<connectionStrings>元素中缺少 SQL Server 连接字符串。您需要在与 EF 连接字符串相同的位置添加类似<add name="DefaultConnection" connectionString="data source=MYCOMP\MYCOM;initial catalog=MY;persist security info=True;user id=sa;password=1*34" providerName="System.Data.SqlClient" />的连接字符串。
