Question

I have two data types:

class MyDataType {
    public int Id;
    private int Field;
    public String AnotherFieldOrProperty;
    // + there are some methods
}

class MyDataTypeDescriptor {
    public int Id;
    public String Description;
}

I need to convert List<MyDataType> to List<MyDataTypeDescriptor> such a way:
MyDataTypeDescriptor.Id = MyDataType.Id
MyDataTypeDescriptor.Description = MyDataType.ToString();

I guess C# can do that very easy and fast in just one line of code, but I don’t know how because I’m not familar with such advanced techniques. Would someone help me please?

Thanks

Answer 1

This should do it (where myDataTypes is your List<MyDataType>):

List<MyDataTypeDescriptor> myDataTypeDescriptors = 
     myDataTypes.Select(x => new MyDataTypeDescriptor 
                                 { 
                                      Id = x.Id, 
                                      Description = x.ToString() 
                                 }).ToList();
