Need simple conversion from C++ to C#

Question

New to C#. Could someone interpret the following C++ code into C# so that I can do some console application debugging. I can't quite figure out how the Console.Read() and Console.ReadLine() functions could do this:

#include <iostream>
using namespace std;

int main
{
     int input;
     cout << "Enter value:";
     cin >> input;
     return 0;
}

I've tried the following code but it just prints out the askey value and then halts.

int test;
Console.Write("Enter value:");
test = Console.Read();
Console.Write(test);
Console.ReadLine();

Answer 1

using System.IO;

[STAThread]

static int Main ( string[] args )
{
    Console.Write ( "Enter Name" );
    string text = Console.ReadLine ( );
    return 0;
}

I don't quite understand what int input is doing up there.

Answer 2

Using System;

[STAThread]

static int Main(string[] args)
{
int test;
Console.WriteLine("Enter value:");
string value = Console.ReadLine();
int.TryParse(value, out test);

/// Do some process with test.

return 0;
}

There is no direct .NET equivalent to "cin".  You are free to use the 'SimulateCin' helper class that we use in our conversions:

using System;

int test()

{

int input;

Console.Write("Enter value:");

input = SimulateCin.ReadToWhiteSpace(true);

return 0;

}

internal static class SimulateCin

{

private static bool goodlastread = false;

internal static bool LastReadWasGood

{

get

{

return goodlastread;

}

}

internal static string ReadToWhiteSpace(bool skipleadingwhitespace)

{

string input = "";

char nextchar;

if (skipleadingwhitespace)

{

while (char.IsWhiteSpace(nextchar = (char)Console.Read()))

{

}

input += nextchar;

}

while ( ! char.IsWhiteSpace(nextchar = (char)Console.Read()))

{

input += nextchar;

}

goodlastread = input.Length > 0;

return input;

}

}
