Sure, here's a version which doesn't use any string functions:

using System;
using System.Text;

class Test
{
static void Main()
{
string s1 = "soon iam gonna be king of .net" ;
var sb = new StringBuilder();

int end = s1.Length - 1;

for(int i = s1.Length - 1; i >= 0; i--)
{
if (s1[i] == ' ')
{
for (int j = i + 1; j <= end; j++) sb.Append(s1[j]);
sb.Append(" ");
end = i - 1;
}
}

s1 = sb.ToString();
Console.WriteLine(s1); ;
Console.ReadKey();
}
}

You can reverse a string like this:

using System;

class Test
{
static void Main()
{
string s1 = "soon iam gonna be king of .net" ;
string[] words = s1.Split(' ');
Array.Reverse(words);
s1 = String.Join(" ", words);
Console.WriteLine(s1);
Console.ReadKey();
}
}

It's also possible to do it more compactly using LINQ but as I'm not sure whether you've learnt that yet I've stuck to 'traditional' code.
