[update]解析输入文字：



一个简单的粘贴解决方案是：



拆分文字到元素，你将获得一个字符串数组

{日期，时间，拉特，......，2002/01/10，00：44：51.53 ，40.4415....}



然后查看值并使用它们。

如果您确定这些将在传入文本中出现的顺序，那将是很好的。

这可以很容易地实现：

[update] Parsing the input text:

One simple solution for your pasting is:

Split the text to elements, you will get an array of string
{ "Date", "Time", "Lat", .... , "2002/01/10", "00:44:51.53", "40.4415" .... }

then go through the values and use them.
that will be good if you are sure about the order in which those will appear in the incoming text.
This can be achieved easily like this:

string[] values = Regex.Split(YourText, @"\D+");
foreach (string val in values)
{
   // do stuff with the elements ...
}

// OR this:
double LAT = Convert.ToDouble(values[11]); // take the elements according to their position.
double LON = Convert.ToDouble(values[12]);
// and so on ...

但是，我强烈建议您学习C＃Regex 以适应由于文本格式化而未来发生的任何需求，以及一般来说，在我看来，Regex对于开发人员来说几乎是必不可少的工具。 />

However, I strongly suggest you learn C# Regex to accommodate for any needs that rise due to the formatting of the text, future changes and generally speaking, Regex in my opintion is pretty much a must tool for a developer.
