将 2 个文本文档中的替换/复制/重复行替换为第 3 个答案

【问题标题】：Replace/Copy/Duplicate Lines from 2 text documents into a 3rd将 2 个文本文档中的替换/复制/重复行替换为第 3 个
【发布时间】：2011-09-28 22:56:46
【问题描述】：

我有两个 .txt 文档，我想在其中一个文件中搜索第二个文件中的密钥。如果找到键，我想用第二个文件中键后面的文本替换匹配项。另外，我想根据文件中的数字添加“T”或“B”。

这是第一个文件的示例：

   1       0010    SOMETEXT/NUMBERS    SOME TEXT, TEXT
   .2      0020    SOMETEXT/NUMBERS    SOME TEXT, TEXT, TEXT
   1       0020A   SOMETEXT/NUMBERS    SOME TEXT,TEXT
   .1      2000    SOMETEXT/NUMBERS    SOME TEXT,TEXT, TEXT
   ..3     9123A   SOMETEXT/NUMBERS    SOME TEXT
   ...     ...     ...                 ...

这是第二个文件的示例：

  0010    ABCD EFG
  0020    C01
  0020A   C02, C3, C004, C9901, C938, C12
  2000    R123, R13, D34 
  9123A   SOMETEXT
  ...     ...

从这两个文件中，我想使用第二个文件中的“键”（在每个新行的开头）。所以在这个例子中，键是：0010、0020、0020A、2000、9123A。获得密钥后，我想搜索第二列中的第一个文本文档以查看是否有匹配项。如果有匹配项（在这种情况下它们都匹配），我想替换第一个文档中的文本并使用更新的文本创建一个新文档。另外，如果第二个文件中的键后面有多个值，我想将这些行复制下来。请看下面，看看我的意思。

新文档如下所示：

   1       ABCD EFG   SOMETEXT/NUMBERS    SOMETEXT, TEXT
   .2      C01        SOMETEXT/NUMBERS    SOME TEXT, TEXT, TEXT
   1       C02        SOMETEXT/NUMBERS    SOME TEXT,TEXT             //--------------------
   1       C3         SOMETEXT/NUMBERS    SOME TEXT,TEXT             // Copied the lines
   1       C004       SOMETEXT/NUMBERS    SOME TEXT,TEXT             // down if there are
   1       C9901      SOMETEXT/NUMBERS    SOME TEXT,TEXT             // multiple values in
   1       C938       SOMETEXT/NUMBERS    SOME TEXT,TEXT             // document 2.
   1       C12        SOMETEXT/NUMBERS    SOMETEXT,TEXT              //--------------------
   .1      R123       SOMETEXT/NUMBERS    SOME TEXT,TEXT, TEXT       //--------------
   .1      R13        SOMETEXT/NUMBERS    SOME TEXT,TEXT, TEXT       // COPIED ALSO
   .1      D34        SOMETEXT/NUMBERS    SOME TEXT,TEXT, TEXT       //--------------
   ..3     SOMETEXT   SOMETEXT/NUMBERS    SOME TEXT
   ...     ...     ...                 ...

另外，如果键以“A”结尾，我想在上面的字符串末尾添加一个“T”。如果键不以“A”结尾，我想在上面的字符串末尾添加一个“B”。

几行示例：

   .1      R123       SOMETEXT/NUMBERS    SOME TEXT,TEXT, TEXT         B       //key was 2000
   .1      R13        SOMETEXT/NUMBERS    SOME TEXT,TEXT, TEXT         B       //key was 2000
   .1      D34        SOMETEXT/NUMBERS    SOME TEXT,TEXT, TEXT         B       //key was 2000
   ..3     SOMETEXT   SOMETEXT/NUMBERS    SOME TEXT                    T       //key was 9123A

【问题讨论】：

那是相当多的代码。你能把它缩减到理解问题所必需的最低限度吗？
我在帖子底部添加了代码说明。我想保留代码，以防有人想跑进去看看它发生了什么。

【解决方案1】：

我能够生成您所期望的文件。我不确定这是否对您的代码有帮助，因为我对格式有点困惑，但希望它会。可能有一种方法可以清理此代码，但我没有时间深入研究您的问题。我希望这会有所帮助，如果没有，我很抱歉。

我有第一个包含数据的文件：

1 0010 xxxxxxxxxxxxxx xxxx Txxx, Txxx
.2 0020 yyyyyyyyyyyyyyyy yyyy yyyy, yyyy, yyyy
1 0020A rrrrrrrrrrrrrrrrrr rrrr rrrr,rrrr
.1 2000 wwwwwwwwwwwwwwwwwww wwww wwww,wwww, wwww
..3 9123A vvvvvvvvvvvvvvvvvvvvv vvvv vvvv

那么第二个文件包含这个数据：

0010 ABCD EFG
0020 C01
0020A C02, C3, C004, C9901, C938, C12
2000 R123, R13, D34
9123A H33333

然后代码生成包含此数据的第三个文件：

1 ABCDEFG  xxxxxxxxxxxxxxxxxxTxxx,Txxx
.2 C01  yyyyyyyyyyyyyyyyyyyyyyyy,yyyy,yyyy
1 C02  rrrrrrrrrrrrrrrrrrrrrrrrrr,rrrr T
1 C3  rrrrrrrrrrrrrrrrrrrrrrrrrr,rrrr T
1 C004  rrrrrrrrrrrrrrrrrrrrrrrrrr,rrrr T
1 C9901  rrrrrrrrrrrrrrrrrrrrrrrrrr,rrrr T
1 C938  rrrrrrrrrrrrrrrrrrrrrrrrrr,rrrr T
1 C12  rrrrrrrrrrrrrrrrrrrrrrrrrr,rrrr T
.1 R123  wwwwwwwwwwwwwwwwwwwwwwwwwww,wwww,wwww
.1 R13  wwwwwwwwwwwwwwwwwwwwwwwwwww,wwww,wwww
.1 D34  wwwwwwwwwwwwwwwwwwwwwwwwwww,wwww,wwww
..3 H33333  vvvvvvvvvvvvvvvvvvvvvvvvvvvvv T

代码如下所示：

        var strFileName = DisplayFile("choose file 1", "*.txt", null);
        var strFileName2 = DisplayFile("choose file 2", "*.txt", null);

        StreamReader srInputOne = File.OpenText(strFileName);

        List<string> recNew = new List<string>();

        while (srInputTwo.Peek() > -1)

            twoHash.Add(vals[0], vals[0]);
        }

        srInputTwo.Close();

        while (srInputOne.Peek() > -1)
        {
            string line = srInputOne.ReadLine();
            string[] parts = line.Split(' ');

            if(!twoHash.ContainsKey(parts[1]) && parts[0] != "1")
            {
                swOutput.WriteLine(line);

                if (parts[1].Contains('A'))
                {
                    join = join + " T";
                }
                else
                {

                }

                if (!oneHash.ContainsKey(parts[1]))
                {
                    oneHash.Add(parts[1], join);
                }
            }

        }

        srInputOne.Close();

        srInputTwo = File.OpenText(strFileName2);

        while(srInputTwo.Peek() > -1)
        {
            string line2 = srInputTwo.ReadLine();

            string[] parts2 = line2.Split(' ');

            string join2 = string.Empty;

            for (int i = 1; i < parts2.Length; i++)
            {
                join2 = join2 + " " + parts2[i];
            }

            if (oneHash.ContainsKey(parts2[0]))
            {
                if (join2.Contains(','))
                {
                    for (int j = 1; j < parts2.Length; j++)
                    {

                        swOutput.WriteLine("1 " + parts2[j].Trim(',') + " " + oneHash[parts2[0]].ToString());
                    }
                }
                else

        }

        srInputTwo.Close();
        swOutput.Close();

【讨论】：

我认为现在的问题是这两个文件是否包含所有相同的部分。因此，如果第二个文件中不包含每 4 个字母数字，如果哈希中的“密钥”不匹配，我将如何保留它们？
如果我理解你的 ?你想知道如果第二个文件中的一行不在哈希集中怎么办。然后我会在其中添加一个 if 语句，如果 oneHash 不包含密钥，那么只需按原样打印该行，或者让它写出您需要的任何数据。
是的。我会把它放在第二个文件偷看的while循环中吗？还是我会把它放在别的地方？
你是对的。那是你应该把它放在哪里。检查对答案的编辑是您可以使用的想法。
好的，我添加了。但是由于某种原因，它似乎没有达到第二个 while 循环
