Implicit conversions 2. Explicit Conversions 3. Difference between Parse() and TryParse() Implicit conversion is done by the compiler: 1. When there is no loss of information if the conversion is done 2. If there is no possibility of throwing exceptions during the conversion Example: Converting an int to a float will not loose any data and no exception will be thrown, hence an implicit conversion can be done. Where as when converting a float to an int, we loose the fractional part and also a possibility of overflow exception. Hence, in this case an explicit conversion is required. For explicit conversion we can use cast operator or the convert class in c#. Implicit Conversion Example using System; class Program { public static void Main() { int i = 100; // float is bigger datatype than int. So, no loss of // data and exceptions. Hence implicit conversion float f = i; Console.WriteLine(f); } } Explicit Conversion Example using System; class Program { public static void Main() { float f = 100.25F; // Cannot implicitly convert float to int. // Fractional part will be lost. Float is a // bigger datatype than int, so there is // also a possiblity of overflow exception // int i = f; // Use explicit conversion using cast () operator int i = (int)f; // OR use Convert class // int i = Convert.ToInt32(f); Console.WriteLine(i); } } Difference between Parse and TryParse 1. If the number is in a string format you have 2 options - Parse() and TryParse() 2. Parse() method throws an exception if it cannot parse the value, whereas TryParse() returns a bool indicating whether it succeeded or failed. 3. Use Parse() if you are sure the value will be valid, otherwise use TryParse()
