返回异常值

Question

为什么这段代码不能编译？
它给了我错误:

并非所有代码路径都返回一个值

码:

public bool isUserProfileHashed(string username)
{
    bool isHashed = false;
    MembershipUser u = null;
    u = Membership.GetUser(username);
    if (u != null)
    {
        try
        {
            u.GetPassword();                   
        }
        catch (Exception exception)
        {
            // An exception is thrown when the GetPassword method is called for a user with a hashed password
            isHashed = true;
            return isHashed;
        }
        return isHashed;
    }

你忘了在if 之外放一个返回,把它放在if结束的括号之后

public bool isUserProfileHashed(string username)
{
    bool isHashed = false;
    MembershipUser u = null;
    u = Membership.GetUser(username);
    if (u != null)
    {
        try
        {
            u.GetPassword();                   
        }
        catch
        {
            // An exception is thrown when the GetPassword method is called for a user with a hashed password
            isHashed = true;
        }
    }
    return isHashed;
}
