“对象”不包含“处置”的定义

Question

protected override void Dispose(bool disposing)

In the line above I am getting an error.

The Error is:

windowformapplication.form1.Dispose(bool): not suitable method found to override

Answer 1

1)You might have renamed your class Form to class Form1 without renaming your designer file ie Partial class Form.designer.cs to Partial class Form1.designer.cs
2)Your InitializeComponent(); would have deleted or commented in your windowformapplication.form1() constructor.

Or try adding following code in your designer.cs.

 /// <summary> 
    /// Clean up any resources being used.
    /// </summary>
    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
    }

Answer 2

Be sure that your Form1.cs extend from Form. Such as public partial class Form1 : Form{..}
