c# - Array element is maybe not set -


in method below set string smdrext tmp[3]. however, tmp[3] seems empty because "index outside bounds of array.". before set it, can change exist make sure program not halt again due this?

public void writetocsv(string line, string path) {      string[] tmp = line.split(',');     string smdrext = tmp[3];      if (ext.contains(convert.tostring(smdrext)))     {        file.appendalltext(path, line + "\n");      }  }

please try below code snippet.

public void writetocsv(string line, string path) {     if (!string.isnullorempty(line))     {         string[] tmp = line.split(',');         if (tmp.length > 3)         {             string smdrext = tmp[3];              if (ext.contains(convert.tostring(smdrext)))             {                 file.appendalltext(path, line + "\n");             }         }     }  }

let me know if concern.
