Property Value
Type: System::Int64The number of bytes returned by the request. Content length does not include header information.

The ContentLength property contains the value of the Content-Length header returned with the response. If the Content-Length header is not set in the response, ContentLength is set to the value -1.
The following example displays the value of this property.
#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(); } /* The output from this example will vary depending on the value passed into Main but will be similar to the following: Content length is 1542 Content type is text/html; charset=utf-8 Response stream received. <html> ... </html> */
