问题描述
如何将'String ^'转换为'const char *'?
how to convert 'String^' to 'const char*'?
String^ cr = ("netsh wlan set hostednetwork mode=allow ssid=" + this->txtSSID->Text + " key=" + this->txtPASS->Text);
system(cr);
错误:
1 IntelliSense: argument of type "System::String ^" is incompatible with parameter of type "const char *"
推荐答案
您可以使用类:
You can do this using the msclr::interop::marshal_context
class:
#include <msclr/marshal.h>
然后:
String^ something = "something";
msclr::interop::marshal_context ctx;
const char* converted = ctx.marshal_as<const char*>(something);
system(converted);
转换的缓冲区
ctx
超出范围。
但在你的情况下,更容易调用一个等效的托管API :
But in your case it would be much easier to just call an equivalent managed API:
System::Diagnostics::Process::Start("netsh", "the args");
