long         


        

Answer 1

You can also use long.TryParse and long.Parse.

long l1;
l1 = long.Parse("1100.25");
//or
long.TryParse("1100.25", out l1);

Answer 2

long is internally represented as System.Int64 which is a 64-bit signed integer. The value you have taken "1100.25" is actually decimal and not integer hence it can not be converted to long.

You can use:

String strValue = "1100.25";
decimal lValue = Convert.ToDecimal(strValue);

to convert it to decimal value

Answer 3

http://msdn.microsoft.com/en-us/library/system.convert.aspx

l1 = Convert.ToInt64(strValue)

Though the example you gave isn't an integer, so I'm not sure why you want it as a long.
