C＃“不包含带有'1'参数的构造函数”

Question

I've posted something like this a bit ago and it helped out but i had issues afterwards and couldn't do anything. SO I'M BACK!

Time time1;
private void btnNewTime_Click(object sender, EventArgs e)
        {
            Time time1 = new Time(Convert.ToInt32(txtHour.Text.Trim(), Convert.ToInt32(txtMin.Text)));


        }

and in the time class:

        public Time()
        {
            hour = 12;
            minute = 00;
        }//end of Time

        public Time(int Hour, int Minute)
        {
            hour = Hour;
            minute = Minute;
        }//end of Time

It's suppose to go into the parameterized constructor (the second one) But i get the error:

"does not contain a constructor that takes '1' arguments"

Answer 1

这是一个错字，一个错误的括号。

Time time1 = new Time(Convert.ToInt32(txtHour.Text.Trim()), Convert.ToInt32(txtMin.Text));

Answer 2

Time time1 = new Time
    (
      Convert.ToInt32(txtHour.Text.Trim()), 
      Convert.ToInt32(txtMin.Text)
    );

Answer 3

Looks like you're missing a parenthesis after the first trim to close the Convert.ToInt32 (Also lose one of the last parenthesis on the end).

And, your first construct of Time can be:

public Time()
  :this(12,0)
{
}

Or, if you have VS2010/.NET4 you can now use optional parameters :

public Time(int Hour = 12, int Minute = 0)
{
  hour = Hour;
  minute = Minute;
}

Answer 4

You are only providing 1 argument to the constructor:

Time time1 = new Time(Convert.ToInt32(txtHour.Text.Trim(), Convert.ToInt32(txtMin.Text)));

You need to close the first arguments 2nd set of parenthesis:

Time time1 = new Time(Convert.ToInt32(txtHour.Text.Trim()), Convert.ToInt32(txtMin.Text));

Answer 5

它的错字：

Time time1 = new Time(Convert.ToInt32(txtHour.Text.Trim()), Convert.ToInt32(txtMin.Text));
