How can I copy a variable which is of type IBuffer in C# (UWP app) to a string? The IBuffer itself doesn't seem to have any methods. It has Length which seems to be the correct value. But I cannot see the value in debugger (says requires Native debugging). Below is the class. I need to get Data.
public sealed class MagneticStripeReaderTrackData : IMagneticStripeReaderTrackData
{
public IBuffer Data { get; }

Steps To Read A File: Open a file using the function fopen() and store the reference of the file in a FILE pointer. Read contents of the file using any of these functions fgetc(), fgets(), fscanf(), or fread(). File close the file using the function fclose().
Note that a string is basically an array of chars, terminated by '\0' (NUL). So in this case, buffer is indeed a string. You would want to copy the string only if you want to keep the original and modify the second (or keep a copy of original and then modify buffer).
You can use the scanf() function to read a string. The scanf() function reads the sequence of characters until it encounters whitespace (space, newline, tab, etc.).
using printf() If we want to do a string output in C stored in memory and we want to output it as it is, then we can use the printf() function. This function, like scanf() uses the access specifier %s to output strings. The complete syntax for this method is: printf("%s", char *s);
For example you can use it like this:
var dataReader = Windows.Storage.Streams.DataReader.FromBuffer(Data);
var output = dataReader.ReadString(Data.Length);
