只打印1行到文本框，而不是所有語句c＃

-1

我試圖從我的文件打印到文本框的所有真實的語句。出於某種原因，只有1行出現。我看不到錯誤或錯過了支架。只打印1行到文本框，而不是所有語句c＃

我有單選按鈕，我已經分配了一個變量然後打印到正在工作的文檔。我用.toString（）;因爲我得到一個錯誤，無法將字符串更改爲int，當時我試圖在txtbox中顯示這個摘要。

//if radio button is checked write to file 
      if (rdoIndoor.Checked == true) 
      { 
       rdoIndoor.Text = iIndoor.ToString(); 
       sw.WriteLine(rdoIndoor.Text); 
      } 
      else 
      { 
       rdoOutdoor.Text = iOutdoor.ToString(); 
       sw.WriteLine(rdoOutdoor.Text); 
      } 

      //if radio button is checked write to file 
      if (rdoFree.Checked == true) 
      { 
       rdoFree.Text = iFree.ToString(); 

       sw.WriteLine(rdoFree.Text); 
      } 
      else 
      { 
       rdoPriced.Text = iPriced.ToString(); 

       sw.WriteLine(rdoPriced.Text); 
      }

代碼：

     txtSummary.Text = "Music events were most popular  this year" + Environment.NewLine; 
        } 
        else 
        { 
         txtSummary.Text = "Theatre events were most popular this year" + Environment.NewLine; 
        } 

        //find out if free or pri string line = string.Empty; 
     while ((line = sr.ReadLine()) != null) 
     { 
      for (int iCount = 0; iCount < sMonths.Length; iCount++) 
      { 


       //conditions 
       if (iCount == 2) 
       { 
        sMonths[iCount] = sr.ReadLine(); 

        //find out which type of event was more popular within the year 

        if (iCountDance > iCountArt && iCountDance > iCountMusic && iCountDance > iCountTheatre) 
        { 
         txtSummary.Text = "Dance events were most popular this year" + Environment.NewLine; 
        } 
        else if (iCountArt > iCountDance && iCountArt > iCountMusic && iCountArt > iCountTheatre) 
        { 
         txtSummary.Text = "Art events were most popular this year" + Environment.NewLine; 
        } 
        else if (iCountMusic > iCountDance && iCountMusic > iCountArt && iCountMusic > iCountTheatre) 
        {ced events were more popular this year 
        if (iPriced > iFree) 
        { 
         txtSummary.Text = "Priced events were more popular this year" + Environment.NewLine; 
        } 
        else if (iFree > iPriced) 
        { 
         txtSummary.Text = "Free events were moree popular this year" + Environment.NewLine; 
        } 

        iAttendanceTotal = iAttendance * iAttendance; 
        txtSummary.Text = "At least " + iAttendanceTotal + " people attended events over the year" + Environment.NewLine; 
       }

文本框文本到文件可以嗎？但文本文本到文本框不是，是嗎？ –

@LP。 Gonçalves是的，它之前是從文件到列表框，但由於for循環它只是重複循環，所以我改爲閱讀文本框，它不再起作用。 – Lorna

替換此

txtSummary.Text =...

有了這個：

txtSummary.Text +=

因爲每次你分配新值，它都會用新值替換存儲值。

希望它有幫助！
