C#調用C++寫的Dll時的運作時錯誤解決

兩個錯誤：

1. Run-Time Check Failure #0 - The value of ESP was not properly saved across a

function call. This is usually a result of calling a function declared with one

calling convention with a function pointer declared with a different calling convention

先把dll的項目屬性中C/C++->Code Generation->Basic Runtime Checks的屬性改為Default

檢視一下你的dll中的函數，如果函數傳回是采用某個局部變量，需要把這些傳回的局部變量都聲明為static

問題解決!!
