打开OpenFileDialog后如何读取文件？

Question

我无法在if语句中找到任何方法来读取文本文件。这是代码;

 private void button1_Click(object sender, EventArgs e)
        {           
            OpenFileDialog BrowseFile1 = new OpenFileDialog();
            BrowseFile1.Title = "Select a text file";
            BrowseFile1.Filter = "Text File |*.txt";
            BrowseFile1.FilterIndex = 1;
            string ContainingFolder = AppDomain.CurrentDomain.BaseDirectory;
            BrowseFile1.InitialDirectory = @ContainingFolder;
            //BrowseFile1.InitialDirectory = @"C:\";
            BrowseFile1.RestoreDirectory = true;
            if (BrowseFile1.ShowDialog() == DialogResult.OK)
            {

            }

我只想从我在OpenFolderDialog窗口中选择的文本文件中获取全文。

Answer 1

 string text = System.IO.File.ReadAllText(BrowseFile1.FileName);

另一种可能性是使用StreamReader：

只需通过BrowseFile1.FileName更改文件位置。
