Initializing System::String with a managed array of char

I'm trying out my first project with visual C++, and I'm having a hard time figuring out a way to initialize a String from an array of char. I am taking an unsigned 32 bit integer as an IP address and generating the text equivalent of it. I felt it was easier to define an array of the maximum size, and parse the address into the array one element at a time then initialize a String based on the final null terminated character array than try to concat an existing String with the characters as I parse.

I am getting 

IP_validate.cpp(170): error C2664: 'System::String::String(const wchar_t *)' : cannot convert parameter 1 from 'cli::array<Type> ^' to 'const wchar_t *'
1>          with
1>          [
1>              Type=char
1>          ]

as an error, and I'm having a very hard time implementing a solution. One promising way I found online was using Encoding::Convert, but I have yet to figure out how to actually make that work. Copy & pasting my code looks like a mess in the forum, so here is the important bits (The parsing of the numbers works fine, please assume that the array temp_ip_slate correctly contains the values for the IP address and is null terminated). 

array<char>^ temp_ip_slate = gcnew array<char>(16); 
//An easier way to construct the ascii IP address (through array[element])

String^ temp_ip_string = gcnew String(temp_ip_slate); 
//The string used to construct the IP address, initialized with our finished IP address
return(temp_ip_string); //Return the finished String back

You can see what I would LIKE to do, but there is no method to construct a String like that. What would be the easiest way to accomplish this?
