獲取特定值從文本文件無法正常工作

Question

我有讀入內存zpllabel.txt文件，但我想從文本文件的所有^ FO值，並添加到它是用戶進入以抵消打印機的價值。

^XA^MCY^PRD,D,D^MMT,N^XZ

^XA^ID*.*^XZ 

所以對於標籤的示例第五行需要是FO43如果用戶輸入的10的偏移值，需要爲23，如果他進入-10作爲偏移值，我在處理TEXTFILES一個小白在C＃請幫

我有這樣的代碼，取代了對文本的：

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()); 
    } 

，所以我想完成 1）閱讀的文本文件到內存 2什麼的）找到的所有值「 FO「 3）增加或減少什麼用戶輸入 4該值），將其發送到文本框 5）後來我發送文本斑馬打印機

我想：

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++) 
{

好吧，你問題非常模糊，你的代碼與你提出的問題沒有任何關係，但這可以幫助你找到你所要求的替代品。

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);
