テキストファイルの特定の部分/行を更新したい..
私はこのコードを持っていますが、動作しません:
public static void UpdatingMethod()
{
string text = File.ReadAllText("fileone.txt");
text = text.Replace("old value", "new stuff");
File.WriteAllText("fileone.txt", text);
}
public static void WritingMethod()
{
int count = 0;
while (count < 10)
{
Console.Write(" Enter your Name: ");
Name = Console.ReadLine();
Console.Write(" Enter your ID: ");
ID = int.Parse(Console.ReadLine());
Console.Write(" Enter your Age: ");
Age = int.Parse(Console.ReadLine());
Console.Write(" Enter your E-mail: ");
Email = Console.ReadLine();
StreamWriter Sw = new StreamWriter("fileone.txt", true);
string output = string.Format("Thank you for registration! Your Submitted information are:" + Environment.NewLine + "Name: {0}"
+ Environment.NewLine + "ID: {1}" + Environment.NewLine + "Age: {2}" + Environment.NewLine + "E-mail: {3}", Name, ID, Age, Email);
Console.WriteLine(output);
Sw.WriteLine(output + Environment.NewLine);
Console.ReadLine();
Sw.Close();
count++;
}
}
