C# Question
Pass Parameters To Method
I am getting an error of
Error CS7036 There is no argument given that corresponds to the required formal parameter 'b2' of 'Form1.checkInfo(PointF, PointF, PointF, PointF, ref PointF)' WindowsFormsApplication1
when I attempt to pass parameters to a method. This is my syntax, and to me it looks like
b2private void button1_Click(object sender, EventArgs e)
{
Point[] points = new Point[] { new Point { X = -100, Y = 0 }, new Point { X = 0, Y = 0 } };
PointF returnedPoint = new PointF();
for (int i = 0; i < points.Count(); i++)
{
float X1value = points[i].X;
float X2value = points[i-1].X;
float Y1value = points[i].Y;
float Y2value = points[i-1].Y;
checkInfo(new PointF(X1value, Y1value), new PointF(X2value, Y2value), ref returnedPoint);
}
}
bool checkInfo(PointF a1, PointF a2, PointF b1, PointF b2, ref PointF returnedPoint)
{
//Do stuff here
}

Your method checkInfo(PointF a1, PointF a2, PointF b1, PointF b2, ref PointF returnedPoint) takes 5 parameters, but you call it checkInfo(new PointF(X1value, Y1value), new PointF(X2value, Y2value), ref returnedPoint) with only 3 parameters. The error message complains about missing parameters.
Please see my comments below:
private void button1_Click(object sender, EventArgs e)
{
Point[] points = new Point[] { new Point { X = -100, Y = 0 }, new Point { X = 0, Y = 0 } };
PointF returnedPoint = new PointF();
for (int i = 0; i < points.Count(); i++)
{
float X1value = points[i].X;
float X2value = points[i-1].X;
float Y1value = points[i].Y;
float Y2value = points[i-1].Y;
// Error located here: Only 3 parameters passed - You need to pass 2 more instances of 'PointF'
checkInfo(new PointF(X1value, Y1value), new PointF(X2value, Y2value), ref returnedPoint);
}
}
// Takes 5 parameters
bool checkInfo(PointF a1, PointF a2, PointF b1, PointF b2, ref PointF returnedPoint)
{
//Do stuff here
}
