Is there a way to disable implicit casts from UInt32 to char?

Question

I am working on code that takes as input a ton of ascii text defined by specific protocol. The original author interpreted \"string(1)\" datatypes in the original protocol

Answer 1

No, the behavior allowing the expression theChar == 7 is part of the C# specification, and can't be changed.

Note that the actual implicit conversion here is from char to int, not from int to char.

Here's how it works:

• The literal 7 has type int.
• The variable theChar has type char.
• To apply the == operator to the two expressions, the compiler must choose an == operator.
  • There is no == operator that takes a char as the first argument and an int as the second.
  • There is no implicit conversion from int to char (because such a conversion can lose information).
  • There is an implicit conversion from char to int.
  • The compiler converts the char expression to int, and uses the == operator that takes two ints.
