詳細(xì)介紹C#調(diào)用API
該例程演示了C#調(diào)用API函數(shù)，而且回調(diào)函數(shù)的參數(shù)包含結(jié)構(gòu)體，使用C#的委托和IntPtr方法實(shí)現(xiàn).由于我使用C#剛兩天,這是我寫的***個C#程序,因此例程寫的可能有點(diǎn)粗糙,但是編譯和運(yùn)行完全沒有問題.CMPP2.0的API封裝成了標(biāo)準(zhǔn)C調(diào)用API的方法，提供以下三個接口，使用的時候只要有CMPPAPI.dll就可以了.

C#調(diào)用API,如何聲明結(jié)構(gòu)體,如何使用委托實(shí)現(xiàn)回調(diào)函數(shù),如何實(shí)現(xiàn)使用自定義結(jié)構(gòu)體作為參數(shù)的回調(diào)函數(shù),請仔細(xì)查看例程源碼。注意:CMPPAPI.dll要和可執(zhí)行文件放到同一個目錄下,或者放到可執(zhí)行文件能找到的目錄,或者放到系統(tǒng)目錄下(如:C:\windows \system32).
