1)您可以使用Guid作为文件名.

2)您可以保留一个计数器，并为每个保存的文件增加计数器.

1) You can use Guid as your file name.

2) You can keep a counter and increment that for each file saved.

尝试一下

string FileName=Test+DateTime.Now.ToString().Replace("/", "").Replace(".", "").Replace(":", "").Replace(" ", "")+".txt";
string text = "Test string to write inside the text file";
System.IO.File.WriteAllText(@FileName, text);

使用FileName + HH:MM:SS
连接文件 fileName024658

试试这个

Concatenate file with FileName + HH:MM:SS
fileName024658

Try this

string path = @"D:\";
string fileName = "TestFile" + DateTime.Now.ToString().Replace("/", "").Replace(":", "").Replace(" ", "") + ".txt";
File.Create(path + fileName);
