C#多行Texbox [英] C# Multiline Texbox

问题描述

我正在使用一个新的C#.Net程序寻求帮助.我将单选按钮和列表框的参数传递给只读的多行文本框.数据传输工作正常，但是，一个选择会覆盖另一个选择，我希望它可以在多行"文本框中的换行"上显示单独选择的值.我已经看过"\ n \ r"，但看起来好像新值将始终覆盖先前选择的值.

任何帮助将不胜感激

问候

解决方案

我建​​议购买一些有关C#的书，并阅读以涵盖这些基础知识.切勿使用\ n \ r，而应使用可移植的Environment.NewLine.如果设置属性，则更改其值.

tb.Text ="1" + Environment.NewLine;
tb.Text ="2" + Environment.NewLine; ;这将用2代替1
tb.Text = tb.Text +"1" + Environment.NewLine; ;这将添加文本末尾.

除了Christian的正确答案外，还可以使用+ =

TextBox1.Text += Environment.NewLine;

来连接字符串.您还可以使用string.Format 如果要串联很多字符串，则可以使用 StringBuilder [ ^ ]类

我很确定"\ r \ n"是正确的组合(而不是"\ n \ r")，尽管您应该使用Environment.NewLine.试试这个:

 textBox1.AppendText(Environment.NewLine + " )； 

另外，下次再输入一些代码，我们也许可以为您提供更好的帮助.

Hi,
I seek some assistance please with a new C#.Net program I''m playing with. I am passing arguments from radio buttons and Listbox''s into a Multi line textbox which is read only. The transfer of data works fine, however, one selection overwrites the other and I''d like it to display the individually selected values on a NewLine within the Multiline text box. I have looked at the "\n\r" but it appears as if the new value will always overwrite the previously selected value.

any help will be appreciated

regards

I''d recommend buying some books on C# and reading them to cover these sort of basics. NEVER use \n\r, use Environment.NewLine, which is portable. If you set a property, you change it''s value.

tb.Text = "1" + Environment.NewLine;
tb.Text = "2" + Environment.NewLine; ; this will REPLACE the 1 with the 2
tb.Text = tb.Text + "1" + Environment.NewLine; ; This ADDS the text on the end.

in addition to Christian''s correct answer, strings can also be concatenated by using +=

TextBox1.Text += Environment.NewLine;

You can also use string.Format

TextBox1.Text = string.Format("{0}{1}", TextBox1.Text, Environment.NewLine);

If you''re concatenating a lot of strings, you can use the StringBuilder[^] class too.

I''m pretty sure "\r\n" is the correct combination (not "\n\r"), although you should use Environment.NewLine. Try this:

textBox1.AppendText(Environment.NewLine + "New Line");

Also, next time put some code and we may be able to help you better.
