Cannot convert int to system.iformatprovider

What I have tried:

textData = File.ReadAllBytes(@"C:\Users\Admin\Desktop\k1.txt");

           int[] intArray = new int[textData.Length];

           for (int i = 0; i < textData.Length; i++)
           {
               intArray[i] =Convert.ToInt16(textData[i],16);
           }

Solution 1

You seem to be trying to convert each byte to an integer, assuming that each byte contains a value between '0' and '9' inclusive.
If so, then this will do it:

int[] intArray = new int[textData.Length];

for (int i = 0; i < textData.Length; i++)
    {
    byte b = textData[i];
    if (b >= (byte)'0' && b <= (byte)'9')
        {
        intArray[i] = (int)(b - '0');
        }
    }

Then add the hex values as well:

for (int i = 0; i < textData.Length; i++)
    {
    byte b = textData[i];
    if (b >= (byte)'0' && b <= (byte)'9')
        {
        intArray[i] = (int)(b - '0');
        }
    if (b >= (byte)'A' && b <= (byte)'F')
        {
        intArray[i] = (int)((b - 'A') + 10);
        }
    }
