如何在C＃中打开任何文件 [英] How do I open any file in C#

问题描述

我制作了一个文件浏览器，我想将文件加载到代码编辑器中，有点像Visual Studio中的解决方案浏览器。我有这段代码打开一个文件夹浏览器对话框，并使文件浏览器像这样一个。我想要它，这样如果你双击一个文件，它将在编辑器中打开该文件。我正在使用树状视图和图像列表。

I making a file browser which I want to load files into the code editor, a bit like the solution explorer in visual studio. I have this piece of code which opens a folder browser dialog and makes a file browser like this one. I want it so that if you double-click a file it will open that file in the editor. I am using a tree view and an image list.

private void openFolderToolStripButton_Click(object sender, EventArgs e)
        {
            FolderBrowserDialog obd = new FolderBrowserDialog();
            if (obd.ShowDialog() == DialogResult.OK)
            {
                path = obd.SelectedPath;
                Console.WriteLine("path is found");
                Console.WriteLine(path.ToString());
                if (path != "")
                {
                    flowLayoutPanel1.Width = 200;
                    DirectoryInfo directoryInfo = new DirectoryInfo(path);
                    DirectoryInfo[] directories = directoryInfo.GetDirectories();
                    foreach (FileInfo file in directoryInfo.GetFiles())
                    {
                        
                        if (file.Exists)
                        {
                            TreeNode nodes = treeView1.Nodes[0].Nodes.Add(file.Name);
                            SetImageExtension(file.Name, nodes);
                        }
                    }

                    if (directories.Length > 0)
                    {
                        foreach (DirectoryInfo directory in directories)
                        {
                            TreeNode node = treeView1.Nodes[0].Nodes.Add(directory.Name);
                            node.ImageIndex = node.SelectedImageIndex = 0;
                            foreach (FileInfo file in directory.GetFiles())
                            {
                                if (file.Exists)
                                {
                                    TreeNode nodes = treeView1.Nodes[0].Nodes[node.Index].Nodes.Add(file.Name);
                                    SetImageExtension(file.Name, nodes);
                                }
                            }
                        }
                    }
                }
            }
        }

我尝试了什么：



好​​吧，我有这个，不知道如何实际阅读文件。

What I have tried:

Well, I have this for and not sure how to actually read from the file.

private void TreeView_NodeDoubleClick(object sender, MouseEventArgs e)
        {
            string nodeText = treeView1.SelectedNode.Text;
            string nPath = path + @"\" + nodeText;
            using (var fileStream = new FileStream(nPath, FileMode.Open, FileAccess.Read))
            {
                Console.WriteLine(nPath);
            }
        }

推荐答案

谷歌搜索是你的朋友： c＃从文件中读取 [ ^ ]

Google Search is your friend: c# read from a file[^]

问题是如何在c＃中打开任何文件

Question is how do I open any file in c#

而google没有给你答案，没有例子，没有什么？

and google gave you no answer, no example, no nothing ?

引用：

我不希望它是一个文本文件，我希望它是.html，.css，.js或.php文件。它是同一个过程

I don't want it to be a text file I want to it to be .html, .css, .js or .php files. Would It be the same process

所有这些文件都是文本文件，文件扩展名无关紧要。



记住：谷歌是你的朋友。

至少在此之前做基础研究，我们不是免费的搜索服务。

All those files are text files, the file extension doesn't matter.

remember: Google is your friend.
At least do basic research before asking here, we are not a free search service.
