推荐答案
我们不能回答：文本文件没有表格，行或列 - 它几乎没有线条（这些只是对特定系统内容的基本解释。
所以我们不能告诉你如何从文本文件中读取两个数据表，因为我们不知道数据是如何组织的，并且表示这是一行并且这是一个新表的开始，更不用说这是一个专栏和这是下一栏。你需要坐下来看看你的数据并完成所有这些工作。但是当然，哪一次，你将有90％你自己整理出来并准备好编码的文件处理算法......：笑：
在两个DataGridViews中显示它很简单：将你文件中的每个表加载到一个单独的DataTable，并将其设置为DataGridView.DataSource参数 - 系统将采用ca.为你做的。
We can't answer that: a text file doesn't have tables, rows or columns - it barely has lines (and those are just a basic interpretation of the content for a particular system.
So we can't tell you how to read two tables of data from a text file because we have no idea how the data is organised and whet indicates that "this is a row" and "this is the start of a new table", much less what says "This is a column" and "this is the next column". You need to sit down, look at your data and work all of that out. But which time, of course, you will have 90% of the file processing algorithm sorted out yourself and ready for coding...:laugh:
Displaying in two DataGridViews it trivial: load each table from your file into a separate DataTable, and set it as the DataGridView.DataSource parameter - the system will take care of it for you.
