文件由其他进程使用

我正在使用 #C。如果我这样做

TextWriter tw = new StreamWriter("trades.txt");
// write a line of text to the file
tw.WriteLine(DateTime.Now);
// close the stream
tw.Close();

它将收到一个错误，指出该文件被其他进程使用：

怎么办？我想用命令来计算我已经得到的行数，但这会出现错误。

假设这是一个新文件，您可以尝试以下操作

string filePath = @"c:'"trades.txt"";
using (StreamWriter sw = new StreamWriter(filePath, true))
{
    tw.WriteLine(DateTime.Now.ToString());
    tw.Flush();
}

另一种方法可以做到这一点 

using System.IO;
using(FileStream fileStream = new FileStream(@"c:'trades.txt", FileMode.Open))
{
   fileStream.Write(DateTime.Now.ToString());
   fileStream.Flush();
}
