你需要使用 ADO.NET [ ^ ] - OleDb [ ^ ]。



方法与此处描述的相同：访问Microsoft .NET应用程序中的Office数据 [ ^ ]。唯一的区别是你需要处理（在这种情况下） * .dat 文件作为文本文件。

要获得正确的结果，有时需要创建 schema.ini文件 [ ^ ]，其中包含有关文件一般格式的信息，如：列名和数据类型信息以及其他一些数据特征。



请参阅我的过去的答案 [ ^ ]也可以找到示例代码。



试试！

You need to use ADO.NET[^] - OleDb[^].

The way is the same as is described here: Accessing Microsoft Office Data from .NET Applications[^]. The only difference is that that you need treat (in this case) *.dat file as a text file.
To get proper result, sometimes it needed to create schema.ini file[^], which contains information about general format of the file, like: the column name and data type information, and several other data characteristics.

See my past answers[^] too to find sample code.

Try!
