嘗試從文本文件中調用時GUI程序崩潰

我不確定這裏出現了什麼問題。我的程序可以讀取「文本」並將其放入標題中，但不會出現任何問題，但它會崩潰並且在更改大小或顏色之前不會更改大小或顏色。我試過要求我的同學們提供這方面的幫助，但他們說我的所有代碼看起來都是正確的。嘗試從文本文件中調用時GUI程序崩潰

什麼是場[0]的值，[1]，[2]？ – 2012-02-22 16:42:37

請提供Data.txt文件的內容 – 2012-02-22 16:45:56

red，small，texttest – Bya413 2012-02-24 17:20:20

fields：可能是空的，文件的結尾？任何文件打開錯誤？試圖在它已經在後臺打開時再次打開它？

更多的信息可能會對您有所幫助。像其他人所說的那樣，字段[0] - [2]的值是什麼？你收到什麼錯誤？它看起來像我會像一個錯誤，你會收到的是，你的索引超出了字段數組的界限...給我們一些更多的信息，我們可以更好地幫助你。

嘗試這樣

using (FileStream infile = new FileStream(FILENAME, FileMode.Open, FileAccess.Read)) 
{ 
    using (StreamReader reader = new StreamReader(infile)) 
    { 
     string recordIn = reader.ReadLine(); 
     while (recordIn != null) 
     { 
      fields = recordIn.Split(DELIM); 
      stuff1.color = fields[0]; 
      stuff1.size = fields[1]; 
      stuff1.text = fields[2]; 

      if (fields[0] == "red") 
      { 
       this.BackColor = System.Drawing.Color.Red; 
      } 
      if (fields[0] == "blue") 
      { 
       this.BackColor = System.Drawing.Color.Blue; 
      } 
      if (fields[0] == "yellow") 
      { 
       this.BackColor = System.Drawing.Color.Yellow; 
      } 
      if (fields[1] == "large") 
      { 
       this.Size = new System.Drawing.Size(500, 500); 
      } 
      if (fields[1] == "small") 
      { 
       this.Size = new System.Drawing.Size(300, 300); 
      } 
      this.Text = fields[2]; 

     } 
    } 

}
