将richtextbox保存到文件C# [英] save richtextbox to file C#

问题描述

我无法从Richtextbox保存到.txt文件

I am having trouble saving from richtextbox to .txt file

下面是代码:

if (richTextBox1.Text != String.Empty)
            {
                string dir = @"c:\\logs\\" + DateTime.Today.ToString("dd_MMM_yy");
                string path = @"c:\\logs\\" + DateTime.Today.ToString("dd_MMM_yy") + "\\" + DateTime.Now.ToString("HH.mm.ss") + ".txt";
                if (!Directory.Exists(dir))
                {
                    Directory.CreateDirectory(dir);
                }

                if (!File.Exists(path))
                {
                    File.Create(path);
                    richTextBox1.SaveFile(path, RichTextBoxStreamType.RichText);
                }

            }
            else
                MessageBox.Show("ERROR");

我要去哪里错了?它说它无法访问文件，因为它正在被另一个进程使用...欢迎任何帮助

where I am going wrong ?! It says it cannot access the file because it is being used by another process... Any help would be welcome

推荐答案

您可以避免创建文件行，因为 SaveFile 会为您创建文件.

you can avoid create file line because SaveFile will create file for you.

File.Create 将返回文件的打开流，您需要先关闭它，然后才能再次访问.如果您仍然需要使用创建文件，请执行以下操作

File.Create will return open stream for the file, you need to close it before access again. Do as below If you need to use create file anyway

using(File.Create(path));
richTextBox1.SaveFile(path, RichTextBoxStreamType.RichText);
