问题描述
即时通讯参考:Microsoft.press.microsoft.ado.net.4.step.by.step.oct.2010
我试图将linq转换为sql,但出现此错误:类型"ADODOTNET.Emp"未映射为表."
im refering: Microsoft.press.microsoft.ado.net.4.step.by.step.oct.2010
I was trying linq to sql, but i get this error:"The type ''ADODOTNET.Emp'' is not mapped as a Table."
public class SalesOrder : DataContext
{
// ----- Constructor establishes database connection.
public SalesOrder(string connectionString) : base(connectionString) { }
// ----- Table definitions to link with database.
public Table<Emp> Employee;
}
Emp表有4个列:
ID
fname
Lname
薪金
我在linq查询下面射击:
Emp table has 4 coloumns:
ID
fname
Lname
Salary
I was firing below linq query:
using (SalesOrder context = new SalesOrder(linkToDB.ToString()))
{
var linqresult = from cu in context.Employee
select new { CustomerID = cu.ID, CustomerName = cu.LNAME };
}
