我正在使用实体框架创建一个C#MVC4.5项目,并在我的Web.config中设置了以下连接字符串:
<connectionStrings>
<add name="Entities"
connectionString="metadata=res://*/PersistenceModel.csdl|res://*/PersistenceModel.ssdl|res://*/PersistenceModel.msl;provider=System.Data.SqlClient;provider connection string="data source=.\sqlexpress;initial catalog=TravPro;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework""
providerName="System.Data.EntityClient" />
</connectionStrings>
然后我按如下方式访问此字符串:
string con = ConfigurationManager.ConnectionStrings["Entities"].ConnectionString;
WebSecurity.InitializeDatabaseConnection(con,
"UserProfile",
"UserId",
"UserName",
true);
这会抛出“路径中的非法字符”异常:
[ArgumentException: Illegal characters in path.]
System.IO.Path.CheckInvalidPathChars(String path, Boolean checkAdditional) +10631190
System.IO.Path.Combine(String path1, String path2) +42

WebMatrix.WebData.WebSecurity.InitializeProviders(DatabaseConnectionInfo connect, String userTableName, String userIdColumn, String userNameColumn, Boolean autoCreateTables) +51
WebMatrix.WebData.WebSecurity.InitializeDatabaseConnection(String connectionStringName, String userTableName, String userIdColumn, String userNameColumn, Boolean autoCreateTables) +51
TravPro.Web.Filters.SimpleMembershipInitializer..ctor() in c:\Work\trunk\TravPro\TravPro.Web\Filters\InitializeSimpleMembershipAttribute.cs:43
有人可以协助并告诉我哪些字符需要转义或如何解决此异常?

您存储的连接字符串用于实体框架 - 它不是“常规”ADO.NET连接字符串。实体框架连接字符串包含常规ADO.NET连接字符串(provider connection string=.....
中的位) - 但除此之外还有更多内容。
WebSecurity
需要常规ADO.NET连接字符串作为输入 - NOT 实体框架连接字符串。
因此,要解决此问题,您需要将WebSecurity
的第二个连接字符串添加到配置文件中的<connectionStrings>
部分:
<connectionStrings>
<add name="Entities"
connectionString="metadata=res://*/PersistenceModel.csdl|res://*/PersistenceModel.ssdl|res://*/PersistenceModel.msl;provider=System.Data.SqlClient;provider connection string="data source=.\sqlexpress;initial catalog=TravPro;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework""
providerName="System.Data.EntityClient" />
<add name="RegularADONET"
connectionString="data source=.\sqlexpress;initial catalog=TravPro;integrated security=True;MultipleActiveResultSets=True;"
</connectionStrings>
然后使用WebSecurity
的第二个“常规”ADO.NET连接字符串:
string con = ConfigurationManager.ConnectionStrings["RegularADONET"].ConnectionString;
WebSecurity.InitializeDatabaseConnection(con, "UserProfile", "UserId", "UserName", true);

我按照你的方式尝试(@marc_s),但是我仍然有问题,尽管它确实引导我朝着解决方案的方向前进。我将connectionStrings更改为:
<connectionStrings>
<add name="DefaultConnection"
connectionString="data source=.\sqlexpress;initial catalog=TravPro;integrated security=True;MultipleActiveResultSets=True;"
providerName="System.Data.SqlClient" />
<add name="Entities"
connectionString="metadata=res://*/PersistenceModel.csdl|res://*/PersistenceModel.ssdl|res://*/PersistenceModel.msl;provider=System.Data.SqlClient;provider connection string="data source=.\sqlexpress;initial catalog=TravPro;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework""
providerName="System.Data.EntityClient" />
</connectionStrings>
现在一切似乎都很好吃。我创建了一个新的项目模板,运行它,并看到了连接字符串格式的差异。
以下是我的InitializeSimpleMembershipAttribute.cs:
WebSecurity.InitializeDatabaseConnection("DefaultConnection",
"UserProfile",
"UserId",
"UserName",
true);
感谢您指点我正确的方向。
非常爱。

我能看到的唯一问题可能是你的“角色 - 尝试使用单引号
