字符串和COM端口 [英] Strings and COM ports

问题描述

大家好，
感觉有点厚脸皮，因为我得到了答案，但终点线已经在眼前，我只有一点障碍可以克服.

我有这段代码(由mark ... legend提供)在一个字符串输入的字符之间放置一个"x"字符(不要问为什么！).

Hey guys,
Feel a little cheeky because I got an answer but the finishing line is in sight and I just have one little hurdle to get over.

I have this code (supplied by mark...legend) to put an ''x'' character between chars entered on a string (don''t ask why!).

StringBuilder sb = new StringBuilder();
foreach (Char c in textBox1.Text)
{
    sb.Append(c);
    if (!Char.IsWhiteSpace(c))
    {
        sb.Append("x");
        serialPort1.Write(sb.ToString());
    }
}
textBox2.Text = sb.ToString();

剩下要做的就是分别将这些字符发送到com端口.到目前为止，我可以从按键或存储的变量中发送单个字符，但是我需要某种循环来逐个发送上述字符串(sb).
我尝试了很多方法，可以列出它们，但是我似乎没有任何成功.

All is left to do is to send these characters to a com port individually. So far I can send a single char from a keypress or stored variable, but i need some kind of loop to send the above string (sb) one by one.
I''ve tried so many methods, and can list them, but I don''t seem to be having any success.

推荐答案

这是一种方法:

This is one way:

string x = sb.ToString();
foreach (char ch in x)
{
    seriealPort1.Write(ch);
}

或者，使用您的示例:

Or, to use your sample:

StringBuilder sb = new StringBuilder();
foreach (Char c in textBox1.Text)
{
    sb.Append(c);
    serialPort1.Write(c.ToString());

    if (!Char.IsWhiteSpace(c))
    {
        sb.Append("x");
        serialPort1.Write("x");
    }
}
textBox2.Text = sb.ToString();
