当我的代码尝试执行.dbml文件中存在的存储过程时，我得到以下堆栈跟踪。

异常发现传输：System.Data.SqlClient.SqlException：

第 67 行

我唯一的怀疑是多元化本身是如何绊倒的。数据库中没有命名表t_wfe_user_role。它被称为，但随后 Linq在文件的 GUI 中将其t_wfe_user_roles重命名。这个表是一个有两个外键的连接表。t_wfe_user_role.dbml

有任何想法吗！？

这是我调用存储过程的代码片段。通话结束（sp_wfe_transfer_task_force）：

if there is no issue with re generating data model then you can turn off pluralization and the generate class . in visual studio On the Tools menu, click Options.

In the Options dialog box, expand Database Tools.

(Note:Select Show all settings if the Database Tools node is not visible.)

Click O/R Designer.

Set Pluralization of names to Enabled = False to set the O/R Designer so that it does not change class names.

Set Pluralization of names to Enabled = True to apply pluralization rules to the class names of objects added to the O/R Designer.

otherwise You can change the generated name by right-clicking the table in the dbml designer window and selecting properties. There is a field called 'name' with which you should be able to define a custom name.
