How To Generate Random Numbers And Strings in c#

This function can be effectively used for Gnerating Random strings of any length


public string RandomStrings()
{

StringBuilder builder = new StringBuilder();
Random random = new Random();
char ch;
for (int i = 0; i < 10; i++)
{
ch = Convert.ToChar(Convert.ToInt32(Math.Floor(26 * random.NextDouble() + 65)));
builder.Append(ch);
}

return builder.ToString();

}


You can use The following code to generate random numbers

private string RandomString(int size, bool lowerCase)
{
StringBuilder builder = new StringBuilder();
Random random = new Random();
char ch ;
for(int i=0; i==size; i++)
{
ch = Convert.ToChar(Convert.ToInt32(Math.Floor(26 * random.NextDouble() + 65))) ;
builder.Append(ch);
}
if(lowerCase)
return builder.ToString().ToLower();
return builder.ToString();
}
