Conversions in C#

                

1.Implicit

=>Small to Big

=> InBuilt Automatically will Do

Ex:

int numInt = 10;

long numLong = numInt; // Implicit conversion from int to long

2.Explicit (Casting)

=>Big to Small

Ex:

double numDouble = 3.14159;

int numInt = (int)numDouble; // Explicit conversion from double to int (data loss)

3.Convert Class:

=>The Convert class in C# provides methods for converting between different base data types, such as numbers and strings.

string strNum = "123";

int num = Convert.ToInt32(strNum); // String to int conversion

4.Parsing: 

=>For converting from strings to other data types, you can use the Parse methods provided by various data types (like int.Parse, double.Parse, etc.).

Ex:

string strDouble = "3.14";

double numDouble = double.Parse(strDouble); // String to double conversion

5.TryParse:

=> To handle potential parsing errors without throwing exceptions, you can use the TryParse methods, which return a boolean indicating the success of the conversion and store the result in an out parameter.

Ex:

string strInt = "123";

int parsedInt;

bool success = int.TryParse(strInt, out parsedInt);

if (success)

{

    // Conversion successful

}

6.Convert.ChangeType: 

=>The Convert.ChangeType method allows you to convert an object to a specified type at runtime.

Ex:

object obj = 5;

int num = (int)Convert.ChangeType(obj, typeof(int)); // Runtime conversion
