Cast from int to long is interpreted as conversion between the two types. Cast from object to int is interpreted as unboxing a boxed int. It is the same syntax, but it says two different things. In the working cases (int→long, object (boxed int)→int), the compiler knows exactly what code to produce.
16 gru 2009 · An int (aka System.Int32 within the runtime) is always a signed 32 bit integer on any platform, a long (aka System.Int64) is always a signed 64 bit integer on any platform. So you can't cast from a long with a value above Int32.MaxValue or below Int32.MinValue without losing data.
19 mar 2024 · For example, a variable of type long (64-bit integer) can store any value that an int (32-bit integer) can store. In the following example, the compiler implicitly converts the value of num on the right to a type long before assigning it to bigNum. // Implicit conversion.
Type casting is when you assign a value of one data type to another type. In C#, there are two types of casting: Implicit Casting (automatically) - converting a smaller type to a larger type size. char -> int -> long -> float -> double. Explicit Casting (manually) - converting a larger type to a smaller size type.
14 wrz 2021 · Type conversion creates a value in a new type that is equivalent to the value of an old type, but does not necessarily preserve the identity (or exact value) of the original object. .NET automatically supports the following conversions: Conversion from a derived class to a base class.
The process of converting the value of one data type (int, float, double, etc.) to another data type is known as type conversion. In this tutorial, we will learn about C# type conversion with the help of examples.
Implicit Conversion. Implicit conversion is a type conversion that occurs without explicit casting. C# provides implicit conversions for several types, such as: From int to long. From short to int. From byte to int. From sbyte to int. From float to double. From bool to string. Here’s an example of implicit conversion:
