C#: Write an application that computes the area of a circle, rectangle, and cylinder. Display a menu showing the three options. Allow users to input which figure they want to see calculated. Based on the value inputted, prompt for appropriate dimensions and perform the calculations using the following formulas: Area of circle = pi * radius ^ 2 Area of rectangle = length * width Area of cylinder 2 * pi * radius ^ 2 + 2 * pi * radius * height You will create a Windows Forms application that allows for the user to select the type of shape (rectangle, circle or cylinder) and then accept proper data and calculate the appropriate solution. Hint: a group of radio buttons will work very well along with changing the visible property of text boxes on your form. Comment your code for process communicating with clients.

I have written the majority of the code but I am still having trouble with the following lines:

private System.ComponentModel.IContainer components = null; protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } With the red lines being under Dispose

this.SuspendLayout(); Red line under SuspendLayout();

this.AutoScaleDimensions = new System.Drawing.SizeF(9F, 20F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.ClientSize = new System.Drawing.Size(965, 633); this.Controls.Add(this.RbtRectangle); this.Controls.Add(this.Container); this.Controls.Add(this.LblResult); this.Controls.Add(this.BrtShape); this.Controls.Add(this.RbtCylinder); this.Controls.Add(this.RbtCircle); this.Name = "Area_Shape"; this.Text = "Area of Shape"; this.Container.ResumeLayout(false); this.Container.PerformLayout(); this.ResumeLayout(false); this.PerformLayout();

With each line having red lines under all the words after this.

Here is the rest of my code:

namespace Area_Shape { public partial class Area_Shape : Form { public Area_Shape() { InitializeComponent(); } private void Area_Shape_Load(object sender, EventArgs e) { LblHeight.Visible = false; LblLength.Visible = false; LblWidth.Visible = false; LblRadius.Visible = false; LblResult.Visible = false; TxtLength.Visible = false; TxtHeight.Visible = false; TxtRadius.Visible = false; TxtWidth.Visible = false; BtnCalculate.Visible = false; BtnExit.Visible = false; }

} } }

Any help would be appreciated, I would also like to get rid of the try can catch functions but I am not too sure how to make this work without them. Thank you
