how can I convert string to binary data using .net

Question

How can I convert a string variable to a binary data variable using .net 1.1?

I found a way of doing this:

ASCIIEncoding^ ascii = gcnew ASCIIEncoding;
String^ unicodeString = L"This Unicode String* contains two characters with codes outside the ASCII code range, Pi (\u03a0) and Sigma (\u03a3).";
array<Byte>^ binaryData = ascii->GetBytes( unicodeString );

What kind of "binary data"? A PNG picture? An integer representing the sum of the ASCII characters in the string? — DevSolar

i have a string that I want to convert to base64. I need a byte array in order to use Convert::ToBase64String — user1064036

In .NET 1.1, you only have access to the broken Managed Extensions for C++ compiler. It is broken, you should not use it.

However, IIRC, the syntax would be something like:

System::Byte bytes __gc[] = Encoding::ASCII::GetBytes(inputString);
System::String __gc* base64string = Convert::ToBase64String(bytes);

What about this?

byte[] InputbyteArray = Encoding.UTF8.GetBytes(inputString);
string B64String = Convert.ToBase64String(InputbyteArray)

you say you "found" a solution - an hours after I answered, what is the difference between my answer and your solution?

Ben Voigt Over a year ago

Your "solution" isn't in the requested language.

I disagree, it was a .net question not a c++ or clr specific question. The solution is .net, just different syntax - which lets be honest is a trivial conversion.

Finding someone who knows Managed Extensions for C++ is non-trivial.
