Csv. importing to panel

Hi Everyone!

I’m just getting into programming and learning the very basics and mostly hacking together things from here and there building tools to suit my needs.

I’m working on trying to make a very basic .csv reader in C# that in psuedo code does the following:

“If read is true, get the file at specified path and read data as string value.”

Here’s the basic graph/node layout:

Here’s an example of what I would like the data to end up as in a panel:

And here’s the C# code inside the script that I’ve been editing:

    if(read)
    {
    var fileinfo = File.ReadAllLines(path);
      if(fileinfo.Length == 0)
      return;
    var index = -1;

    if(index == -1)
      return;

    var list = new List<string>(fileinfo.Length - 1);
    for(var i = 1;i < fileinfo.Length;i++)
    {
      var dataRow = fileinfo[i].Split(',');
      if(dataRow.Length <= index){
        list.Add(null);
      }else{
        list.Add(dataRow[index].Trim());
      }
    }
    data = list;
    }

It is contained in lines 60-82 and at line 14 I added System.IO

So my question is, am I doing something that is negating my looped values? or am I not looping correctly and thus returning null? Something else?

Thank you for your help! I only know the very basics and enough to be dangerous at this point =/ but I’m eager to learn more!

Oh wow, all I needed was this tiny bit of code. Leaving this here in case it helps anyone else:

Code:

    if(read)
    if(System.IO.File.Exists(file))
    {
      data = System.IO.File.ReadAllText(file);
    }

Raw data (as I wanted):
