.net c# winform打开指定目录,选中目录文件,打开文件

.net c# 打开目录的方法很多

1. 通用方法,可打开目录和文件.但无法选中目录中的文件.

        /// <summary>
        /// 打开目录或者文件,简洁写法
        /// </summary>
        /// <param name="filepath"></param>
        public static void OpenFileTo(string filepath)
        {
            System.Diagnostics.Process.Start("explorer.exe", filepath);
        }

2.打开指定的目录.

        /// <summary>
        /// 打开目录
        /// </summary>
        /// <param name="path">目录路径</param>
        public static void OpenFolder(string path)
        {
            if (string.IsNullOrEmpty(path)) return;
            Process process = new Process();
            ProcessStartInfo psi = new ProcessStartInfo("Explorer.exe");
            psi.Arguments = path;
            process.StartInfo = psi;
            try
            {
                process.Start();
            }
            finally { process?.Close(); }
        }

3.打开指定的目录并选中指定的文件

        /// <summary>
        /// 打开目录且选中文件
        /// </summary>
        /// <param name="filepath">文件的路径</param>
        public static void OpenFolderChkFile(string filepath)
        {
            if (string.IsNullOrEmpty(filepath)) return;
            Process process = new Process();
            ProcessStartInfo psi = new ProcessStartInfo("Explorer.exe");
            psi.Arguments = "/e,/select," + filepath;
            process.StartInfo = psi;
            try
            {
                process.Start();
            }
            finally { process?.Close(); }
        }

4.打开指定的文件

        /// <summary>
        /// 打开文件
         /// </summary>
        /// <param name="filepath">文件的路径</param>
        public static void OpenFile(string filepath)
        {
            Process process = new Process();
            ProcessStartInfo psi = new ProcessStartInfo(filepath);
            process.StartInfo = psi;
            process.StartInfo.UseShellExecute = true;
            try
            {
                process.Start();
            }
            finally { process?.Close(); }
        }

5.针对部分有特殊符号的,如果需要打开目录,并选中文件

        [DllImport("shell32.dll", ExactSpelling = true)]
        private static extern void ILFree(IntPtr pidlList);

        [DllImport("shell32.dll", CharSet = CharSet.Unicode, ExactSpelling = true)]
        private static extern IntPtr ILCreateFromPathW(string pszPath);

        [DllImport("shell32.dll", ExactSpelling = true)]
        private static extern int SHOpenFolderAndSelectItems(IntPtr pidlList, uint cild, IntPtr children, uint dwFlags);

        /// <summary>
        /// 打开路径并定位文件...对于@"c:\aa\A Report - Call ??.mav"这样的，explorer.exe /select,d:xxx不认，用API调整下
        /// 打开文件夹并定位到指定的文件选中，方法加强版，主要是应对路径中含有特殊字符的情况
        /// </summary>
        /// <param name="filepath"></param>
        public static void OpenFileStrong(string filepath)
        {
            if (!File.Exists(filepath) && !Directory.Exists(filepath))
                return;

            if (Directory.Exists(filepath)) Process.Start(@"explorer.exe", "/select,\"" + filepath + "\"");
            else
            {
                IntPtr pidlList = ILCreateFromPathW(filepath);
                if (pidlList != IntPtr.Zero)
                {
                    try
                    {
                        Marshal.ThrowExceptionForHR(SHOpenFolderAndSelectItems(pidlList, 0, IntPtr.Zero, 0));
                    }
                    finally
                    {
                        ILFree(pidlList);
                    }
                }
            }
        }
