当我在Visual Studio项目中添加对我的dll的引用时,我能够使用它,但是当我编译我的代码或尝试运行它时,我得到的是你是否缺少using指令或汇编引用？_错误.我能够确认我的命名空间使用了正确的语句,并且我能够确认dll是否已正确加载.任何人都知道我可能没有这个权利吗？
尝试运行WCF服务导致以下结果.我在http://msdn.microsoft.com/en-us/library/ms733768.aspx页面上尝试了与netsh相关的建议, 并且没有任何工作.请帮忙了解我如何解决这个问题.
提前致谢.

at …OSGP.exe中0x758cd36f处的未处理异常:Microsoft C++异常:内存位置为0x0028ef70的std :: bad_alloc ..
我试图在Visual Studio中执行下面的代码.但是,我一直遇到上面的例外.我添加了一个try catch来帮助我捕获错误,但似乎无济于事.我相信问题与输出窗口中的以下内容有关
First-chance exception at 0x758cd36f in OSGP.exe: Microsoft C++ exception: std::bad_alloc at memory location 0x0019f2f4..
First-chance exception at 0x758cd36f in OSGP.exe: Microsoft C++ exception: std::bad_alloc at memory location 0x0019ec84..

The thread 'Win32 Thread' (0x16dc) has exited with code 0 (0x0).
The program '[448] OSGP.exe: Native' has exited with code 0 (0x0).**
这是代码:
#include <osgDB/ReadFile>
#include <osgViewer/Viewer>
#include <new>
#include …我是C++的新手(来自C#背景),我有一个带有以下签名的函数
void AddBenchNode(ref_ptr<Group> root ,ref_ptr<Node> benches, bool setAttitude = false, float scale_x =.15, float scale_y =15, float scale_z = 15, int positionx = 250, int positiony = 100, int positionz =0 )
{
}
但是当我尝试调用下面的代码时,我得到一个错误,表示函数不带4个参数.
//then I try to call my function like so
AddBenchNode(root, benches, false, 250);
但我得到以下错误消息
错误C2660:'AddBenchNode':函数不带3个参数
会不会理解C++如何做到这一点呢？
我想实现一个函数,它返回它正在操作的类型的值.我该如何做到这一点？
例1:
static T Swap<T>(ref T lhs, ref T rhs)
{
T temp;
temp = lhs;
lhs = rhs;
rhs = temp;
return <T> temp;
}
例2:
public override T GetRandom()
{
return (T)_random.Next(_min, _max);
}
