Question

我正在使用ASP.net MVC。所以我想在渴望时设置用户角色。

所以这是我的控制器

public ActionResult LogOn(LogOnModel model, string returnUrl)
{
    if (ModelState.IsValid)
    {                
        var user = GetuserByname(model.UserName);
        if (user.ToList().Count == 1)
        {
            string dbPassword = user.First().UserPassword.ToString();
            string enterPassword = CreatePasswordHash(model.Password, user.First().Salt.ToString());

            if (dbPassword.ToString().Trim() == enterPassword.ToString().Trim())
            {
                FormsAuthentication.SetAuthCookie(user.First().tblUserRole.RoleName, model.RememberMe);
                Session["logged"] = user.First().Username;


                string roleName = user.First().tblUserRole.RoleName;
                Roles.AddUserToRole(model.UserName, roleName);
                return RedirectToAction("Index", "Home");
            }
        }                
    }            
    return View(model);
}

这是我的webconfig文件

<?xml version="1.0" encoding="utf-8"?>

<configuration>

    <connectionStrings>
        <add name="ApplicationServices1" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" />
        <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" />
        <add name="SKGEntities" connectionString="metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=(local);Initial Catalog=SKG;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
    </connectionStrings>

    <authentication mode="Forms">
        <forms loginUrl="~/Login/LogOn" timeout="2880" />
    </authentication>

    <membership>
        <providers>
            <clear />
            <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="3" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" />
        </providers>
    </membership>

    <profile>
        <providers>
            <clear />
            <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/" />
        </providers>
    </profile>

    <roleManager enabled="true">
        <providers>
            <clear />
            <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/" />
            <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/" />
        </providers>
    </roleManager>

</configuration>

但是有错误，它说......

建立与SQL Server的连接时发生与网络相关或特定于实例的错误

......我不知道如何解决它。

另外如何设置...

 Roles.AddUserToRole(xxx, yyy);

...在我的控制器中？

谢谢。

错误消息表明您的数据库（SQL服务器）无法访问。

您的提供商（角色，成员资格，个人资料）设置为使用ApplicationServices连接字符串，即：

data source=.\SQLEXPRESS;
Integrated Security=SSPI;
AttachDBFilename=|DataDirectory|aspnetdb.mdf;
User Instance=true

...但是你的其他连接字符串是

Data Source=(local);
Initial Catalog=SKG;
Integrated Security=True;
MultipleActiveResultSets=True

...完全是一个不同的数据库服务器。

更改提供程序配置以使用正确的数据库服务器。
