进程无法访问文件“目录\文件”因为它正在被 C# 文件写入器中的另一个进程使用
当我尝试保存现有文件时，我收到此错误：
该进程无法访问该文件，因为该文件正在被另一个进程使用
当文件不存在时它可以工作，但是当我尝试再次写入该文件时，会出现错误。我当时没有访问或使用该文件。
这是代码：
string directory = filepath + "Updates\\" + dir;
if(!Directory.Exists(directory))
{
Directory.CreateDirectory(directory);
}
remarks = remarks.Trim();
remarks = remarks.Replace("\r\n","<br>");
remarks = remarks.Replace(",","|");
string file = directory + "\\" + getIndex(barcode) + ".asdt";
StreamWriter writer = new StreamWriter(file,true);
writer.WriteLine(username + "," + barcode + "," + DateTime.Now.ToString("yyyy-MM-dd HH.mm")+ "," + remarks);
writer.Close();
当我检查它时，线路上出现错误：
StreamWriter writer = new StreamWriter(file,true);
这可能是什么原因？
I receive this error when ever I attempt to save on the existing file:
the process can not access the file because it is being used by another process
It works when a file doesn't exist, but when I attempt to write in it again the error shows up. I'm not accessing or using the file that time.
here is the code:
string directory = filepath + "Updates\\" + dir;
if(!Directory.Exists(directory))
{
Directory.CreateDirectory(directory);
}
remarks = remarks.Trim();
remarks = remarks.Replace("\r\n","<br>");
remarks = remarks.Replace(",","|");
string file = directory + "\\" + getIndex(barcode) + ".asdt";
StreamWriter writer = new StreamWriter(file,true);
writer.WriteLine(username + "," + barcode + "," + DateTime.Now.ToString("yyyy-MM-dd HH.mm")+ "," + remarks);
writer.Close();
When I checked it the error occurs on the line:
StreamWriter writer = new StreamWriter(file,true);
what could be the cause of this?

您的程序可能没有正确处理文件流，从而使文件保持打开状态。
使用
using语句确保正确处置：Your program is probably not disposing of the file stream properly, keeping the file open.
Use the
usingstatement to ensure proper disposal:或者您可以在关闭后使 writer 对象无效。
Or you can nullify the writer object after closing.
尝试在
writer.Close();之前使用writer.Flush();try to use
writer.Flush();beforewriter.Close();
