嗨,我是 C# 新手,我的第一个 Windows 窗体应用程序有问题。
我有来自串行端口的数据,并制定了一种处理数据并将其存储到 3 个不同字符串数组中的方法。我无法解决的是如何将数组中的数据显示到它们自己的单独文本框中,我只想显示当前索引位置指向的数组中的数据。
我的 Windows 窗体设计中有 3 个文本框,它们已经命名为:
,我想显示变量 ,并textBoxmag
在
它们相应textBoxlat
的文本框中。textBoxlon
string[] mag
string[] lat
string[] lon
请帮助我,尽管对于更有经验的 C# 程序员来说这似乎很简单,但我仍然坚持这一点。下面是我的代码:
using System;

using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;

using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
string RxString;// where the raw serial data is stored
string[] mag = new string[1000];//where magnetic data is stored
string[] lat = new string[1000];//where latidude data is stored
string[] lon = new string[1000];///where longitude data is stored
string ends = "\r\n";//end of data sentence identifier
string starts = "G";//start of data sentence identifier
int i; //index lat data
int j;//index lon data
int k;//index mag data
public Form1()
{
InitializeComponent();

this.Invoke(new EventHandler(DisplayText));//invoke allows it to call function diplay text

{
if ((RxString.Length > 36))//if there is aleast one string sentence
{
if (RxString.EndsWith(ends))// if the string ends with "\r\n" process the string
serialPort1.Close();//close serial port
lat[i] = RxString.Split(',')[0].Substring(4);// extract latitude store in string array
i++;//increment index of latitude data array
lon[j] = RxString.Split(',')[2];// extract longitude store in string array

RxString = null;//Reset raw data string
serialPort1.Open();//open serial port ready for new string sentence
}
}
else RxString = null;// if the raw data string sentence does not start with "G" reset the array
