C＃IndexOutOfRange問​​題，可能很簡單

Question

由於這個原因，把我的頭從牆上掉下來。即使在重新包裝數組中有190個項目，我在cell [rcell] = repack [counter]處得到錯誤。所以你不能分配給元素cell[rcell]，因爲它不存在

 private string csvtogrid(string input) 
    { 
     input = input.Replace("\r", ",").Substring(2).TrimEnd(',').Trim().Replace("\n", ",").Replace(",,,", ",").Replace(",,",","); 
     string[] repack = input.Split(','); 
     string[] cell = { }; 
     int rcell = 1; 
     for (int counter = 1; counter < repack.Length; counter++) 
     { 
      if (rcell < 4) 
      { 
       cell[rcell] = repack[counter]; 
       rcell++; 
      } 
      procgrid.Rows.Add(cell[1], cell[2], cell[3]); 
      rcell = 1; 
     } 
     richTextBox1.Text = input; 
     return null; 
    }

你cell數組爲空。

string[] cell = { }; 

你應該給它一個大小，當你初始化是足夠大：

string[] cell = new string[4];
