【问题描述】:
我正在做一个小项目,它是 java 和 .net dll 的互操作性。
重点:
我只有一个 java 文件,它调用使用 C#、CPP 和 MCPP 创建的 .net dll ..
该程序只是一个hello world程序..
我只是参考下面提到的网站。
http://www.codeproject.com/Articles/378826/How-to-wrap-a-Csharp-library-for-use-in-Java
http://www.codeproject.com/Articles/13093/C-method-calls-within-a-Java-program
最后我只是得到了一些想法,最后做了一些错误。
编码:
#using "mscorlib.dll"
#using "CSharpHelloWorld.netmodule"
using namespace System;
public __gc class HelloWorldC
{
public:
// Provide .NET interop and garbage collecting to the pointer.
CSharpHelloWorld __gc *t;
HelloWorldC() {
t = new CSharpHelloWorld();
// Assign the reference a new instance of the object
}
// This inline function is called from the C++ Code
void callCSharpHelloWorld() {
t->displayHelloWorld();
}
};
错误:
Error 1 error C4980: '__gc' : use of this keyword requires /clr:oldSyntax command line option
Error 2 error C3699: 'interior_ptr' : cannot use this indirection on type 'CSharpHelloWorld'
Error 3 error C2750: 'CSharpHelloWorld' : cannot use 'new' on the reference type; use 'gcnew' instead
Error 4 error C2440: '=' : cannot convert from 'CSharpHelloWorld *' to 'CSharpHelloWorld ^' 11 WindowsComponentProject
Error 5 error C2011: 'HelloWorldC' : 'class' type redefinition 6 WindowsComponentProject
Error 6 error C3699: '*' : cannot use this indirection on type 'HelloWorldC' 18 WindowsComponentProject
Error 7 error C2750: 'HelloWorldC' : cannot use 'new' on the reference type; use 'gcnew' instead 18 WindowsComponentProject
Error 8 error C2440: 'initializing' : cannot convert from 'HelloWorldC *' to 'HelloWorldC ^' 18 WindowsComponentProject
Error 9 error C2027: use of undefined type 'HelloWorldC' 21 WindowsComponentProject
Error 10 error C2227: left of '->callCSharpHelloWorld' must point to class/struct/union/generic type 21 WindowsComponentProject
我只是在寻找一些解决方案来更改 CLR 属性的网站,但它不起作用请帮助我解决它..提前谢谢!!!
