hello sir
im interestring in CLI programing,however  , how do i convert string^ to char *?

this is the example that call a rest api with httpget,but how do i use httpost and get the string?

#using <System.dll>

using namespace System;
using namespace System::Net;
using namespace System::Text;
using namespace System::IO;

// Specify the URL to receive the request.
int main()
{
   array<String^>^args = Environment::GetCommandLineArgs();
   HttpWebRequest^ request = dynamic_cast<HttpWebRequest^>(WebRequest::Create( args[ 1 ] ));

   // Set some reasonable limits on resources used by this request
   request->MaximumAutomaticRedirections = 4;
   request->MaximumResponseHeadersLength = 4;

   // Set credentials to use for this request.
   request->Credentials = CredentialCache::DefaultCredentials;
   HttpWebResponse^ response = dynamic_cast<HttpWebResponse^>(request->GetResponse());
   Console::WriteLine( "Content length is {0}", response->ContentLength );
   Console::WriteLine( "Content type is {0}", response->ContentType );

   // Get the stream associated with the response.
   Stream^ receiveStream = response->GetResponseStream();

   // Pipes the stream to a higher level stream reader with the required encoding format.
   StreamReader^ readStream = gcnew StreamReader( receiveStream,Encoding::UTF8 );
   Console::WriteLine( "Response stream received." );
   Console::WriteLine( readStream->ReadToEnd() );
   response->Close();
   readStream->Close();
}

you can use class StreamWriter by passing the cli String and Encoding 'Default' what would convert to the current ansi coe page.
