C# integer promotion

WebMar 9, 2024 · Integral promotion prvalues of small integral types (such as char) may be converted to prvalues of larger integral types (such as int ). In particular, arithmetic operators do not accept types smaller than int as arguments, and integral promotions are automatically applied after lvalue-to-rvalue conversion, if applicable.
