Explicit conversion, also known as type casting, is a conversion that must be performed manually. It involves converting a value of one data type to another data type by specifying the desired data type. Explicit conversion is necessary when the target type cannot be implicitly converted from the source type.
Here is an example:
Implicit Conversion:
int num = 1234; double dblNum = (double)num; //explicit conversion from int to double
Implicit conversion is a conversion that is automatically performed by the C# compiler. It involves converting a value of one data type to another data type without the need for explicit code. Implicit conversion is only possible when the target type can be implicitly converted from the source type.
Here is an example:
Type Conversion:
int num = 1234; double dblNum = num; //implicit conversion from int to double
Type conversion refers to the process of converting one data type to another data type. C# supports various types of type conversion, including conversion between primitive data types, conversion between user-defined types, and conversion between built-in types and user-defined types.
Converting Data Types:
Converting data types in C# is essential for working with data effectively. There are various methods for converting data types, including the Parse method, the TryParse method, and the Convert class. The Parse method and TryParse method are used to convert string representations of values to their respective data types. The Convert class can be used to convert values between different data types.
Here is an example:
Understanding conversion in C# is essential for writing efficient and effective programs. By understanding the different types of conversion, you can choose the appropriate method for converting data types in your programs.
string str = "1234";
int num = int.Parse(str); //convert string to int using Parse method
int num2 = Convert.ToInt32("1234"); //convert string to int using Convert class
