后台

dal层
public DataSet getbind()
{
SqlDataProvider sql = new SqlDataProvider();
string sqlSel = "select ID,ModifiedTime,GradeLevel,CreateTime,DepartmentID,PositionID,B.UserID,SuggestSalary,RecuitingNum,RecuitingReasonType,Operation,T.G_CName as DepartmentName,T.GroupID,T1.GroupID,T1.G_CName as PositionName,C.UserID,C.U_CName from sys_AnwerbeformularDate as B INNER JOIN sys_Group AS T ON B.DepartmentID=T.GroupID INNER JOIN sys_Group AS T1 ON B.PositionID = T1.GroupID INNER JOIN sys_User AS C ON B.UserID=C.UserID ";
SqlDataAdapter da = new SqlDataAdapter(sqlSel, GetSqlConnection());
DataSet ds = sql.reDs(sqlSel);
return ds;
}

bll层

public DataSet getbind()
{
SqlDataProvider da = new SqlDataProvider();
return da.getbind();
}

现在后台调用Bll层方法会报这个错，请问下该怎么解决
