How to convert int to uint in C#

How to convert int to uint in C#

In C#, you can convert an int value to a uint value by casting it to uint. Here's an example:

int myInt = -123; uint myUint = (uint)myInt;

In the example above, we first define an int variable myInt with a value of -123. We then cast myInt to uint using the (uint) cast operator and assign the result to a uint variable myUint.

Note that if the int value is negative, the resulting uint value will be a large positive number due to the two's complement representation of signed integers. If the int value is too large to fit in a uint (i.e., greater than UInt32.MaxValue), an OverflowException will be thrown at runtime.

In general, you should only convert an int to a uint if you have a specific reason to do so (e.g., calling a native function that expects a uint parameter). If possible, it's generally better to use signed integer types (int, long, etc.) for arithmetic operations and avoid the potential pitfalls of unsigned integer types.
