[RESOLVED] List in a List - VB Conversion to C#

There is not .ToList() method available with a direct conversion.

Code:

---


///VB Code

lds.Fields = fs.FieldAliases.Keys.ToList

lds.Values = New List(Of List(Of Object))
For i As Integer = 0 To fs.Features.Count - 1
  lds.Values.Add(fs.Features.Item(i).Attributes.Values.ToList)
Next
/////

---

This is what I am trying…not working.

Code:

---


///C# Conversion

foreach (string xyz in fs.FieldAliases.Keys)
 {
  lds.Fields.Add(xyz);
 }

lds.Values = new List<List<Object>>();
List<object> lstValues = new List<object>();
       
lstValues = new List<Object>();
    for (int i = 0; (i
                <= (fs.Features.Count - 1)); i++)
      {
          foreach (object o in fs.Features)
          {
            lstValues.Add(o);
          }
          lds.Values.Add(lstValues);
      }

Try

Code:

---

foreach (string xyz in fs.FieldAliases.Keys)
{
  lds.Fields.Add(xyz);
}

lds.Values = new List<List<Object>>();
       
for (int i = 0; i < fs.Features.Count; i++)
{
  var lstValues = new List<Object>();

  lstValues.AddRange( fs.Features );

  lds.Values.Add(lstValues);
}

Thank You Arjay!
I will study up on .AddRange

Someone also suggested using System.Linq so .ToList would run as in VB.

Thansk again for the quick turnaround.

ToList is also available in C# - it's just that VB allowed you to drop the empty argument list:

Code:

---

lds.Fields = fs.FieldAliases.Keys.ToList();

lds.Values = new List<List<object>>();
for (int i = 0; i < fs.Features.Count; i++)
{
  lds.Values.Add(fs.Features[i].Attributes.Values.ToList());
}

Thanks David....

Try your solution without using System.Linq;
