Short, useless answer: in C#, the "char" type is Unicode, 2 bytes per character. A C++ "char" is in fact the same as a C# "sbyte" (signed byte).
What you really want to know is how to get .NET strings to play nice with C++ strings ("char" arrays). Depending on what your C++ code is doing, you either need to just use .NET strings (i.e. instances of "String") in your managed C++ code, or you need to marshal between the .NET String class and your C++ strings. Here's an MSDN page that might be a good starting point:http://msdn2.microsoft.com/en-us/library/bb384865.aspx
In this newsgroup, Ben, Willy, and maybe one or two others, might have an answer to your question. But this is a perfect example of the sort of question that is completely on-topic in the microsoft.publ ic.dotnet.frame work.interop newsgroup. In that forum, they are doing this sort of thing on a regular basis and you'll get the best, most complete answers posting in that newsgroup.

Thanks for the feedback, I'll re-post the request in the interop
newsgroup
Actually, because you are using the C++/CLI compiler,
microsoft.publi c.dotnet.langua ges.vc is the most appropriate place to
discuss this.
To be useful from C# and other .NET languages, the member functions of your
ref class should accept parameters of type System::String^ . The C++/CLI
compiler provides some pretty simple methods for getting the data as native
C++ characters if you need to, for example the PtrToStringChar s function. 0 1395 This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

i am trying to wrap an unmanaged C++ code to managed one so that i can

Hello,
what is the use-case of parameter "start" in string's "endswith"
method? Consider the following minimal example:
a = "testing"
suffix="ing"
a.endswith(suffix, 2)
Significance of "end" is obvious. But not so for "start".

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
