c#: assigning a .tsv file to a string[,] array -

i'm looking write .tsv file string[,] array using readalllines , subsequent loops i'm running lot of null exceptions , array bounds issues. reason i'm going route because other methods have proved complicated me resolve.
below code i'm working with:

    string[] words;      public form1()     {         initializecomponent();     }      private void button1_click(object sender, eventargs e)     {         words = system.io.file.readalllines(@"file.tsv");         int k = words.count();          string[] count = words[1].split(' ');         int k2 = count.count();          string [,] wordsnew = new string[k, k2];          (int = 0; < k; i++)         {              string[] temp = words[i].split(' ');              (int j = 0; j < k2; j++)             {                 wordsnew[i, j] = temp[j];             }         }     } 

regardless of little changes make , how assign wordsnew, keep running either null exception or index out of bounds errors. see problems or have simpler solutions this?

i'm rather new c# , coding in general may have seen answer in post without realizing it. if that's case, link other relevant topics appreciated!
