提问by Jeagr
I am trying to read a .txt file into a multi-line text box with the following code. I have gotten the file dialog button to work perfectly, but I am not sure how to get the actual text from the fiile into the textbox. Here is my code. Can you help?
我正在尝试使用以下代码将 .txt 文件读入多行文本框中。我已经让文件对话框按钮完美工作，但我不确定如何将文件中的实际文本放入文本框。这是我的代码。你能帮我吗？
private void button_LoadSource_Click(object sender, EventArgs e)
{
Stream myStream = null;
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.InitialDirectory = "c:\";
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
openFileDialog1.FilterIndex = 2;
openFileDialog1.RestoreDirectory = true;
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
try
{
if ((myStream = openFileDialog1.OpenFile()) != null)
{
using (myStream)
{
// Insert code to read the stream here.
}
}
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
}
}
}

if you just need the complete text, you should use the function File.ReadAllText- pass it the FileName/Path selected in the dialoge (openFileDialog1.FileName).
如果您只需要完整的文本，则应使用该函数File.ReadAllText- 将对话框中选择的文件名/路径传递给它 ( openFileDialog1.FileName)。
to load for example the content into a textbox, you can write:
例如要将内容加载到文本框中，您可以编写：
textbox1.Text = File.ReadAllText(openFileDialog1.FileName);
opening and using streams is a little bit more complicated, for that you should look up the using - statement
打开和使用流有点复杂，为此您应该查找 using - 语句
