How to add text in a multiline textbox?
提问by
I have to add details of my file into a multiline textbox. But all the details are getting added in a single line in the text box and not in a vertical sequence. I used Environment.NewLine and also used "\r\n", but it's not of any help. I have ticked the multiline text box in a Windows Forms form and also set it to true but to no avail.
我必须将文件的详细信息添加到多行文本框中。但是所有细节都添加到文本框中的一行中，而不是按垂直顺序添加。我使用了 Environment.NewLine 并使用了 "\r\n"，但它没有任何帮助。我在 Windows 窗体窗体中勾选了多行文本框并将其设置为 true 但无济于事。
My line of code is like this:
我的代码行是这样的：
m_Txt.Multiline = true;
m_Txt.Text = fileInfo.m_Title + "\r\n" +
fileInfo.m_Identifier + Environment.NewLine +
fileInfo.m_TotalTime;

In the Visual Studio resource editor, you can hit "Shift + Enter"
to create a new line, as doing something like "\r\n" will get escaped
out. You will also need to increase the cell height to see both
lines as it does not auto-size.

Not sure why your code would not work unless something else is going on.
不知道为什么除非发生其他事情，否则您的代码将无法工作。
I just created a WinForms project using C#, added a textbox, set it multiline and added the following code - works a charm.
我刚刚使用 C# 创建了一个 WinForms 项目，添加了一个文本框，将其设置为多行并添加了以下代码 - 很有魅力。
textBox1.Text = "a\r\nb";

If you're doing it programatically, append the new line to m_Txt.Lines, which is a string[].
如果您以编程方式执行此操作，请将新行附加到 m_Txt.Lines，它是一个 string[]。
m_Txt.Lines = new string[]{ fileInfo.m_Title, fileInfo.m_Identifier, fileInfo.m_TotalTime};

A cleaner answer is:
更简洁的答案是：
Assuming txtStatus is a textbox:
假设 txtStatus 是一个文本框：
txtStatus.Multiline = True;
txtStatus.Clear();
txtStatus.Text += "Line 1" + Environment.NewLine;
txtStatus.Text += "Line 2" + Environment.NewLine;
Using the built in enumeration means cleaner code.
使用内置枚举意味着更简洁的代码。

I just wrote this code, seems to be working fine.
我刚刚写了这段代码，似乎工作正常。
public void setComments(String comments)
{
String[] aux;
if(comments.Contains('\n')) //Multiple lines comments
{
aux = comments.Split('\n');
for (int i = 0; i < aux.Length; i++)
this.textBoxComments.Text += aux[i] + Environment.NewLine;
}
else //One line comments
this.textBoxComments.Text = comments;
}
