Usage of CHAR data type in a Logical OR expression

[Mini]

Hi Everyone,

This is Mini and I am a beginner in C#.
Was trying out some code something like :


do
{

XXX...
}
while (ch != 'Y' || ch !='y');

where ch is a character data type.
The problem is with this condition the loop goes infinite and not come out when passing value = 'Y' or 'y'.
Then read that logical OR works only with int and enum. Then with implicit type cast to int I tried but the result was same

Please help and guide me how I can establish this condition.

Thanks
Mini

Logical OR Operator: ||

The logical OR operator (||) returns the boolean value true if either or both operands is true and returns false otherwise.

Your expression will always evaluate to true. (y!=Y and Y!=y)
