从文本文件中获取特定值不起作用

本文关键字：不起作用 获取 文本 文件 | 更新日期: 2023-09-27 18:36:11

我有一个 zpllabel.txt 文件，我读入内存，但我想从文本文件中获取所有 ^FO 值，并将用户输入的值添加到其中以偏移打印机。

所以例如，如果用户输入偏移值为 10，标签的第 5 行需要为 FO43，如果他输入 -10 作为偏移值，则需要为 23，我是处理 C# 文本文件的菜鸟，请帮助

我有这段代码来替换一对文本：

 try
{
byte[] file = File.ReadAllBytes("C:''Users''something''Documents''Visual Studio 2013''Projects''zplTest''zplTest''zpllabel3.txt");
 using (MemoryStream memory = new MemoryStream(file))
  {
  using (TextReader reader = new StreamReader(memory))
   {
  string input = reader.ReadToEnd();
     // for (int i = 0; 1 < file.Length; i++)
   {
  using (MemoryStream writermemory = new MemoryStream())
  using (StreamWriter writer = new StreamWriter(writermemory))
    {
   Dictionary<string, string> replacementcollections =
   new Dictionary<string, string>();
   replacementcollections.Add
   ("^FN01^FDCompany^FS", compname);
   replacementcollections.Add
   ("^FN02^FDProduct^FS", stlabel23);
   replacementcollections.Add
   ("^FN03^FDDescription^FS", stlabel24);
   replacementcollections.Add
   ("^FN04^FDNumberIn^FS", stlabel25);
   replacementcollections.Add
   ("^FN05^FDSelectCode^FS", stlabel26);
   replacementcollections.Add
   ("^FN06^FDRotationProduct^FS", stlabel27);
   replacementcollections.Add
   ("^FN07^FD^FS", stlabel28);
   replacementcollections.Add
   ("^FN08^FDUPCCode^FS", stlabel29.TrimEnd());
   replacementcollections.Add
   ("^FN09^FD^FS", stlabel30.TrimEnd());
   replacementcollections.Add
   ("^FN10^FDRotation^FS", "^FN10^FD" + TxtRotcode.Text.Trim() + "^FS");
   replacementcollections.Add
   ("^FN11^FDBestBefore^FS", "^FN11^FD" + TxtBestBefore.Text.Trim() + "^FS");
    replacementcollections.Add
   ("^PQ1,0,1,Y", "PQ" + TxtQty.Text.Trim() + ",0,1,Y");
   string output = input;
   foreach (KeyValuePair<string, string> 
   replacement in replacementcollections)
   { output = output.Replace(replacement.Key, replacement.Value); }
   Label256.Visible = true;
   zplcode.Text = output;
   zplcode.Visible = true;
    writer.Close();
    ZplPreview();
  }
}
}
}
}
catch (Exception ex)
 {
   Console.WriteLine(ex.StackTrace.ToString());
   Console.WriteLine(ex.Message.ToString());
  }

那么我想完成什么1） 将文本文件读入内存2）找到"FO"的所有值3） 用用户输入的内容添加或减去该值4）将其发送到文本框5）我稍后将该文本发送到斑马打印机

我试过了：

 using 
(TextReader reader = new StreamReader(memory)) 
{ 
int offset = Convert.ToInt32(txtOffSet.Text); 
string inputs = reader.ReadToEnd();
Regex r = new Regex("''^FO([0-9]*)", RegexOptions.Singleline); 
string res = r.Replace(Convert.ToString(reader), (input) => "^FO" + (int.Parse(input.Groups[1].Value) + offset).ToString());
 // for (int i = 0; 1 < file.Length; i++) 
{

从文本文件中获取特定值不起作用

好的，你的问题真的很模糊，你的代码与你问的问题无关，但这可以帮助你进行你要求的替换。

string fileContent = File.ReadAllText("path/to/your/file");
int offset = 10; //Store here your offset, positive to add it, negative to subtract it
Regex r = new Regex("''^FO([0-9]*)", RegexOptions.Singleline);
string res = r.Replace(fileContent, (input) => "^FO" + (int.Parse(input.Groups[1].Value) + offset).ToString());
//Now you have the content of the file with the FO replaced with it's new values
Debug.Write(res);
