寻找一种优雅的方式来存储表数据

Question

First post here :) Relatively new to C# coming from C++ originally. I'm currently working with table binaries that use the following format:

struct Table
{
Int32 rowCount;
Int32 columnCount;
customString columnNames[columnCount];
Int32 columnTypes[columnCount];
// Followed by the rowdata, where each type is different based on the columnType (0 = Int32, 1 = float, 2/3 = customString, 4 = Int64
};

struct customString
{
Int16 len;
char str[len]; // There is no null terminator
};

Due to the variable sizes of the strings I cannot define a struct for each table and cast. All tables have different column names too. I'd like to be able to parse every single table in this format and easily be able to read all struct members. How should I go about this without filling in 240 struct members manually for each table?

Thanks a lot!

Answer 1

this might not be to helpful but i would take a closer look at the data in the binary file to break down what and how to present/ hold you data.

the table struct could be much easier build with list for your rows and a row can have in turn list for fields and on the field level you can do all the hard work with figure out the type of the data and what else you need to keep track of.

Again this isnt a soluction ist only an suggestion because what you show us isnt a "final" stage i guess.
