dynamic-linq - EntitySqlException: The command parameter syntax '@0' is not valid

Question

I'm getting this error when I issue this:

DataContext.DBProjectEntities.Projects.Where(xWhere, parameterList.ToArray)

The command parameter syntax '@0' is not valid. Near line 6, column 37.

• xWhere is a string containing value "(ProjectStatuses.Any(DepartmentID = @0))"
• parameterList is Dim parameterList As New List(Of ObjectParameter)

It contains one element with value 1 of type Int32 which corresponds to the type of DepartmentID.

Answer 1

我知道了。我正在使用来自外部程序集的 dunamic.vb。在我的代码中，我有该程序集的导入语句，但我还需要 system.linq.dynamic 的导入
