有点卡在弦上！ [英] a little stuck on strings!

问题描述

嘿人们...

我真的对C#不太好，这几乎是我的第一个裂纹，我很喜欢...但是我很执着，如果可以的话，我将非常感谢您的帮助

我想从textbox1中获取一个字符串，然后单击按钮，将此文本发送到textbox1中最初在字符串中的其他每个字符之后的"x"文本.

换句话说，文本框1会显示这是一个字符串"，然后在按钮blick上，文本框2会显示为2 ="txhxixs xixs xa xsxtxrxixnxg"，这似乎有些愚蠢，但它是用于将数据写入com端口的，但是输出理论将是相同的...

就像这样:

Hey people...

I''m really not very good with c#, this is pretty much my first crack and I like it...but i''m pretty stuck and would really appreciate some help if you could

I''d like to get a string from textbox1, then on button click, send this text to textbox2 with ''x'' after every other character in the string originally in textbox1.

In other words, textbox 1 would read "this is a string", then on button blick, textbox 2 would read 2= "txhxixs xixs xa xsxtxrxixnxg" it may seem a little daft but its for writing data to a com port, but the output theory would be the same...

So something like:

private void button1_Click(object sender, System.EventArgs e) 
{
  char[] inputtext = textBox1.Text.ToCharArray()
  string letterx = ((char)120).ToString();
  for (int i = 0,i<inputtext.length;i++)>
  {
   textBox2.Text = (inputtext, i, 0);   //***
   Thread.Sleep(200);
   textBox2.Text = (letterx.ToString());
   Thread.Sleep(200);
  }
}

到目前为止，我一直在使用serialPort1.Write(inputtext2, i, 1)写入com端口，但这似乎只发送一个字符

我真的很希望你们能提供的任何帮助

欢呼声，

M

So far i''ve been writing to the com port using serialPort1.Write(inputtext2, i, 1), but this only seems to send a single character

i''d really appriciate any help you guys could give

cheers,

M

推荐答案

我不了解写入COM端口的位置或为什么使用Thread.Sleep()?

I don''t understand where the writing to com port comes in or why you are using Thread.Sleep()?

StringBuilder sb = new StringBuilder();
foreach(Char c in textBox1.Text)
{
    sb.Append(c);
    if(!Char.IsWhiteSpace(c))
    {
        sb.Append("x");
    }
}
textBox2.Text = sb.ToString();

嘿向导感谢您的回复...它带来了大量错误，与lamda转换有关( ??)

和嗨马克.基本上，对于一个小型的uni项目，我已经构建了带有LCD控制器的蓝牙寻呼机.它长而纤细的是bt控制器，它接收从comp端口发送的字符，并使用该数据来控制LCD驱动器.

我已对硬件进行了编码，以便在从com端口接收到字符时作出响应，但随后在指令之间必须接收到字符"x"，才能接收到有效的端口信号.

一切工作正常，但是我一次只能在C#应用程序中输入1个字符...因此，我需要分解一个字符串，在每个第二个字符中添加x并发送它，这是有道理的. ?

hey wizzard thanks for the reply...it comes up with a loads of errors, something to do with lamda conversion (??)

and Hi mark. Basically for a small uni project i''ve built a bluetooth pager with an LCD controller. The long and skinny of it is a bt controller recieves a character sent from a comp port and uses that data to control an LCD driver.

I have coded the hardware to respond when a character is recieved from a com port, but then the character ''x'' must be recieved between instructions for a valid port signal to be recieved.

Everything is working well, But i can only enter 1 character at a time into my C# application...hence the reason I need to break down a string, add x to every second character and send it...does that make any sense?

嗯，尝试:

Hmm, try:

textBox2.Text += (inputtext, i, 0);
Thread.Sleep(200);
textBox2.Text += (letterx.ToString());
Thread.Sleep(200);
