char c = getc(stdin); c != -EOF in C#

Question

What is the C# equivalent of the following C++ code?

for (char c = getc(stdin); c != -1; c = getc(stdin))
            if (c == '\n' || c == '\r')
                continue;
            else
                str[p++] = c;
        str[p] = 0;

Answer 1

You are trying to iterate through user input character and if it is \n (\n stands for new line) and \t(\t stands for tab/four blank spaces) then skip it otherwise add it to existing string

In C#, we use Console.Read() to read next character from console, you can use this to read next character from console input, update your code as per your loop and condition.

@Henk used StringBuilder to avoid creating new string everytime, as StringBuilder class is mutable.

You can use @HenkHolterman solution to solve your problem, but this answer will help you to understand his code.

Answer 2

var str = new StringBuilder();
for (int c = Console.Read(); c != -1; c = Console.Read())
{
    if (c == '\n' || c == '\r')
        continue;
    str.Append((char)c);
}
string s = str.ToString();
