[英]Find and move unknown word between particular characters in the string C#
[英]c# find and replace an unknown word between markers/know words
我正在嘗試制作一個程序來替換文件中的單詞,但是當單詞現在是未知單詞時,我不知道如何替換
這是我當文件沒有被修改替換代碼,但是當用戶更改文字/昵稱和想要再次改變它,我需要知道2個字之間的字/昵稱
string path2 = filePath + "\\test\\versions\\"+comboBox1.Text+"\\";
string text = File.ReadAllText(path2+comboBox1.Text+".json");
text = text.Replace("${auth_player_name}", textBox1.Text);
File.WriteAllText(path2+comboBox1.Text+".json", text);
這是詞之間的2個字,我需要更換
--username ${auth_player_name} --version
現在我嘗試未知單詞改為$ {} auth_player_name所以用戶可以再次改變它,這需要那句話,因為我的程序可以編輯相似,但與其他名稱的其他文件
我嘗試了這個但是不工作
text = Regex.Replace(text, "--username \".*\" --ver", "-username \"${auth_player_name}\" --ver");
這是所有的代碼

DirectoryInfo dinfo = new DirectoryInfo(filePath+"\\.minecraft\\versions");
FileInfo[] Files = dinfo.GetFiles("*.json", SearchOption.AllDirectories);
foreach (FileInfo folder in Files)
comboBox1.Items.Add(Path.GetFileNameWithoutExtension(folder.Name));

}
}
}
string path2 = filePath + "\\test\\versions\\"+comboBox1.Text+"\\";
string text = File.ReadAllText(path2+comboBox1.Text+".json");
//Changed to Regex
Regex reg = new Regex("--username ([^-]+)--version");
//using regex.replace function
text = reg.Replace(text, "--username " + textBox1.Text + " --version");
//end edit
File.WriteAllText(path2+comboBox1.Text+".json", text);
更新以將文本變量設置為等於替換變量。
