问题描述

I want output is :

But it only show "lam" in the textBox1. I don't know why. Can you help me to fix it. Thank you so much!!

我的尝试：



我有这段代码：

What I have tried:

I have this code:

private void Form1_Load(object sender, EventArgs e)
{
    string s="hello\amynameis\alam";
    string[] arr = s.Split('\a');
    foreach (string str in arr)
    {
        textBox1.Text = str + "\n";
    }
}

推荐答案

试用：

Try it with :

private void Form1_Load(object sender, EventArgs e)
{
string s="hello\amynameis\alam";
string[] arr = s.Split('\a');
foreach (string str in arr)
{
textBox1.Text += str + "\n"; 
}
} 

查看你的代码：

Look at your code:

foreach (string str in arr)
    {
    textBox1.Text = str + "\n";
    }

每次循环，你用当前字符串覆盖文本框的内容，丢弃所有以前的数据。

您可以尝试：

Each time round the loop, you overwrite the content of the textbox with the current string, discarding all previous data.
You could try:

foreach (string str in arr)
    {
    textBox1.Text += str + "\n";
    }

但它会忽略换行符。

如果它是一个多行文本框，那么你最好这样做：

But it will ignore the newline.
If it's a Multiline text box, then you're better off doing this:

foreach (string str in arr)
    {
    textBox1.AppendText(str + "\n" );
    }

这适用于普通和多行文本框。

This will work for both normal and multi-line textbox.

string s = "hello\amynameis\alam";
string[] arr = s.Split('\a');
textBox1.Text = string.Join(" "+Environment.NewLine, arr);
