I have been on the market for more than a month and have received support and criticism from many friends. I feel it is time to reflect on this version. The manuscript was submitted in February. net 3.0 development, recently started. in the

Local type In C #1.0, a class can only be placed in one file. In C #2.0, a keyword "partial" is used to divide a class into two parts [that is, the implementation of a class can be in multiple files]. The compilation result is exactly the same as
