我正在試着按照http://www.drdobbs.com/cpp/ccli-threading-part-i/184402018的教程來在Visual C++中使用winform進行線程編程。我開了一個Win32控制檯項目並添加一個空的CPP文件到這裏面,我放置代碼如下:在Visual C++/CLI中給出錯誤的線程程序
using namespace System;
using namespace System::Threading;
public class ThreadX{
int loopStart;
int loopEnd;
int dispFrequency;
public:
ThreadX(int startValue, int endValue, int frequency)
{
loopStart = startValue;
loopEnd = endValue;
dispFrequency = frequency;
}
void ThreadEntryPoint()
{
String^ threadName = Thread::CurrentThread->Name;
for (int i = loopStart; i <= loopEnd; ++i)
{
if (i % dispFrequency == 0)
{
Console::WriteLine("{0} : i = {1,10}", threadName, i);
}
}
Console::WriteLine("{0} thread terminating", threadName);
}
};
int main()
{
ThreadX o1 = gcnew ThreadX(0, 1000000,200000);
Thread^ t1 = gcnew Thread(gcnew ThreadStart(o1, &ThreadX::ThreadEntryPoint));
t1->Name = "t1";
ThreadX o2 = gcnew ThreadX(-1000000, 0, 200000);
Thread^ t2 = gcnew Thread(gcnew ThreadStart(o2, &ThreadX::ThreadEntryPoint));
t1->Name = "t2";
t1->Start();
t2->Start();
Console::WriteLine("Primary Thread Terminating");
}
但是這給了我的錯誤,如:
- 錯誤C2726:「gcnew」僅可用於與 管理型
- 錯誤C2440創建一個對象:初始化:不能 從「的ThreadX *」到「的ThreadX」沒有構造轉換可以採取 源類型,或構造函數重載解析模棱兩可
- 錯誤C3364:'System :: Threading :: ThreadStart':委託構造函數的參數無效;代表目標需要爲 指向成員函數的指針
這正是在上市代碼說 - 顯然複製和粘貼錯誤! – doctorlove
@doc:請刪除以下語句,以防止混用C++和C++/CLI:'#include using namespace std;' –
@ me?我沒有添加他們@ user2572521沒有 - 一個災難性的複製和粘貼,並提出額外的東西了錯誤:-) – doctorlove
