我上面的文件中提取子（有多個塊我發現只有2作爲其他人也都是一樣的）我需要與所連接的誤差沿着提取的SQL語句信息。從文本中的C＃塊

到現在我嘗試了下面的代碼

 while ((sql_line = SR.ReadLine()) != null) 
     { 
      string RequiredLine1 = "Sql Stmt"; 
      //sql_line = SR.ReadLine(); 
      if (sql_line.Contains(RequiredLine1)) 
      { 
       //crop out string that comes before: 
       int index = sql_line.IndexOf(":") + 1; 
       sql_line = sql_line.Substring(index); 
      } 
     } 


     while ((error_line = SR.ReadLine()) != null) 
     { 

      string RequiredLine2 = "Error Msg"; 
      // error_line = SR.ReadLine(); 
      if (error_line.Contains(RequiredLine2)) 
      { 
       //crop out string that comes before: 
       int index = error_line.IndexOf(":") + 1; 
       error_line = error_line.Substring(index); 
      } 
     }

但它無法正常工作。請幫忙。

*什麼*不工作？你所做的就是重新分配一個變量，然後什麼都不做 – Sayse

你需要做的是在一個while聲明，否則你將永遠不會得到錯誤行，你需要把SQL語句在不同的參數：

string RequiredLine2 = "Error Msg"; 
    string RequiredLine1 = "Sql Stmt"; 

    while ((sql_line = SR.ReadLine()) != null) 
    { 
     if (sql_line.Contains(RequiredLine1)) 
     { 
      //crop out string that comes before: 
      int index = sql_line.IndexOf(":") + 1; 
      sql_stmt_line = sql_line.Substring(index); 
     } 

     // error_line = SR.ReadLine(); 
     if (error_line.Contains(RequiredLine2)) 
     { 
      //crop out string that comes before: 
      int index = error_line.IndexOf(":") + 1; 
      error_line = error_line.Substring(index); 
     } 
    }

我也把while語句之外的RequiredLine2/1，因爲一遍又一遍地創建相同的字符串沒有意義。

另外，如果你想從文件中提取一個以上的SQL語句，你會需要一些數據結構來保持在
