在C＃中从int转换为bool

Question

int vote;

Insertvotes(objectType, objectId , vote, userID); //calling

For this method call, I want to convert vote to a bool . How can I convert it?

Here is the method signature:

 public static bool Insertvotes(int forumObjectType, 
                                int objectId,
                                bool isThumbUp, 
                                int userID) 
{
    // code...
}

Answer 1

You can try something like

Insertvotes(objectType, objectId , (vote == 1), userID); //calling

Assuming that 1 is voted up, and 0 is voted down, or something like that.

Answer 2

To go from int to boolean

bool isThumbsUp = Convert.ToBoolean(1); //Will give you isThumbsUp == true

To go from boolean to int

int isThumbsUp = Convert.ToInt32(false); //Will give you isThumbsUp == 0

Answer 3

Wouldn't it depend upon semantics of your program. What does isThumbUp indicate? A business rule may say that if there is one vote (ie vote > 0) then its thumbs up or it may say that if there are minimum 5 votes (vote >= 5) then only its "thumbs up". So based on that your call will change - but it would be something like

Insertvotes(objectType, objectId , (vote > [n]), userID);

n being the number of votes needed for thumbs up.

Answer 4

如果投票是真的，如果它们大于零，那么你将它们转换为bool：

Insertvotes(objectType, objectId , vote > 0, userID);
