c# - 生成连续文件名的最佳方法

Question

我正在尝试生成文件名，日志.txt日志1.txt日志2.txt等等

int filenum = 0;
public static void Maker()
{
  string basename = "log";
  string extention = ".txt";
  string finalname = "log.txt";
  for (int i = 0; i < 300; i++)
        {
            using (StreamWriter writer = new StreamWriter(workingDIR + finalname, true))
        {
           // addadder(filenum);
            StringBuilder builder = new StringBuilder();
            builder.Append(base);
            builder.Append(filenum);
            builder.Append(extension);
            finalname = builder.ToString();

        }   } 
}

有没有更好的方法来创建这些类型的文件？第一个文件中不能有数字 EI log.txt谢谢

Answer 1

你可以替换所有这些:

StringBuilder builder = new StringBuilder();
builder.Append(base);
builder.Append(filenum);
builder.Append(extension);
finalname = builder.ToString();

用这个:

finalname = string.Format("log{0}.txt", filenum);

或者用这个:

finalname = string.Format("{0}{1}{2}", basename, filenum, extension);
