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的项目属性中C/C++->Code Generation->Basic Runtime Checks的属性改为Default
2. System.AccessViolationException: 尝试读取或写入受保护的内存。这通常指示其他内存已损坏。
查看一下你的dll中的函数，如果函数返回是采用某个局部变量，需要把这些返回的局部变量都声明为static
问题解决!!
