How to: Convert char * String to System::Byte Array
The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.
The latest version of this topic can be found at How to: Convert char * String to System::Byte Array.
The most efficient way to convert a char * string to a Byte array is to use Marshal class.
Example
// convert_native_string_to_Byte_array.cpp
// compile with: /clr
#include <string.h>
using namespace System;
using namespace System::Runtime::InteropServices;
int main() {
char buf[] = "Native String";
int len = strlen(buf);
array< Byte >^ byteArray = gcnew array< Byte >(len + 2);
// convert native pointer to System::IntPtr with C-Style cast
Marshal::Copy((IntPtr)buf,byteArray, 0, len);
for ( int i = byteArray->GetLowerBound(0); i <= byteArray->GetUpperBound(0); i++ ) {
char dc = *(Byte^) byteArray->GetValue(i);
Console::Write((Char)dc);
}
Console::WriteLine();
}
