Increase performance of IF ELSE condition ASP.NET

static void Main(string[] args)
{
Stopwatch obj=new Stopwatch();
obj.Start();
for(int i=0;i<10000;i++)
{
string str=getdesignation('M');
}

obj.Stop();

console.WriteLine(obj.ElaspsedTicks.ToString());
}


When user login mostly give top wrost performance
public static string getdesignation(char c)
{
if(c=="M")
return "Manager";
else if(c=="W")
return "Worker";

}

public static string getdesignation(char c)
{
if(c=="W")
return "Worker";
else  if(c=="M")
return "Manager";
