fill object data source with class in another project

Question

I'm quit new in c# and linq and I need to fill an ObjectDataSource (in vb.net) with code using a class in another project (in .c#).

I tried doing these things:
1. Add the reference
2. "Imports Project2" in the code behind page.
3. Fill in the load event:

Dim ObjectClass1 As New Class1(ConnectionString)

myODS.TypeName = "ObjectClass1"
myODS.SelectMethod = "GetData"
myODS.SelectParameters("Filter1Name") = New Parameter("Filter1Name", DbType.String, "xxx")

4. The class in the other project looks like this:

   public class Class1
      {
       public string ConnectionString { get; }
   
       public Class1(string connectionString)
       {
           ConnectionString = connectionString;
       }
   
       public IQueryable<MyObject> GetData(string Filter1Name)
         {
          using (MyObjectDataContext dataContext = new  MyObjectDataContext(ConnectionString))
             {
               var Result = dataContext.MyObject.Where(x => x.FILTER_1== Filter1Name).Select(x => new MyObject
                     {
                       Field1 = x.FIELD_1,
                       Field2 = x.FIELD_2
                     });
              return Result;
             }
           }
       }
   

And this is the error I get: ObjectDataSource 'myODS' could not find a non-generic method 'GetData' that has parameters: Filter1Name

What this error means? Is it possible to do what I'm trying to do?

Answer 1

It means it can't find a method on your class called GetInfo() Looking at your class1 definition, you probably meant to make it GetData

Dim ObjectClass1 As New Class1(ConnectionString)

myODS.TypeName = "ObjectClass1"
myODS.SelectMethod = "GetData"
myODS.SelectParameters("Filter1Name") = New Parameter("Filter1Name", DbType.String, "xxx")
