Question

所以这是我当前的代码，我使用该文件写入，创建，然后再次写入，但它说它被另一个进程使用。

    private void btn_Finish_Click(object sender, EventArgs e)
    {
            if((txt_setText.Text != "" || txt_setText.Text != "Enter your text here...") && txt_copyItem.Text != "")
            {
                lbl_error.Visible = false;
                //gets the amount of enties made and sets the int
                amount = Convert.ToInt32(File.ReadAllText(@"Files/data.txt"));
                amount += 1;
                File.WriteAllText(@"Files/data.txt", amount.ToString());

                //execute addCopy function
                addCopy(txt_copyItem.Text, txt_setText.Text);
                MainTab.SelectedIndex = 0;
        }
            else
            {
                lbl_error.Visible = true;
            }

    }

    private void addCopy(string name, string clip)
    {
        string path = @"Files/User/c" + amount.ToString() + ".txt";
        File.Create(path);
        File.WriteAllText(path, (name + "," + clip));
    }

当我操作代码时，我收到此错误：

该进程无法访问文件＆＃39; C：\ Users \ jakey \ onedrive \ documents \ visual studio 2015 \ Projects \ copyboard \ copyboard \ bin \ Debug \ Files \ User \ c1.txt＆＃39;因为它正被另一个进程使用。

我该如何解决？提前致谢：D

解决：

    private void addCopy(string name, string clip)
    {
        string path = @"Files/User/c" + amount.ToString() + ".txt";
        StreamWriter w = new StreamWriter(path);
        w.WriteLine((name + "," + clip));
        w.Close();
    }

刚刚用StreamWriter替换了File.Create（path）

c＃System.IO.File - 进程无法访问该文件
