VB2010中怎么从一个txt文本中读取数据，然后把他们存入excel表中

//初始化 FileInfo 类的实例，它作为文件路径的包装

//判断文件是否存在

C#的就是将excel读到textbox后再导入txt不会的再问我！

直接用下面的代码即可，不需要考虑txt文本有多少行数据，下面的方法会自动识别：
Sub readTxt()
Workbooks.OpenText Filename:="D:\1.txt", Space:=True
End Sub
相关参数：Filename指文件名，Space:=True表示以空格为分割符来载入数据，如果要指定分隔符可使用以下参数：
Tab以制表符为分隔符，Semicolon以分号为分隔符， Comma以逗号为分隔符， 若要自定义分隔符可设置Other参数为True，并在OtherChar参数指定分隔符（若分隔符为多个字符，则以第一个字符为准，其他字符忽略）
下面给出了一个以“/”为分隔符的例子：
Sub readTxt()
Workbooks.OpenText Filename:="D:\1.txt", Other:=True, OtherChar:="/"
End Sub
执行上述代码后，会将txt文件载入一个临时的excel文档里，程序不会 自动帮你保存，你需要自己手动保存这个临时文件。

如果你这个都要问，我还是劝你还是去看看书，

VB我不会用。很抱歉
