WindowsFormsApplication1.Form1.Dispose(bool)': 找不到合适的方法来覆盖

WindowsFormsApplication1.Form1.Dispose(bool)':no suitable method found to override

对于一项作业,我不得不将分形渲染程序从 Java 转换为 C#,我想我已经完成了,但是当我尝试 运行 时,我得到了错误出现在标题中,我不知道为什么会这样。这是渲染器本身的代码,没有错误:

这是用于自动生成的表单设计器的代码,我不确定为什么会出现错误,因为我以前从未有过这样的错误:

namespace WindowsFormsApplication1
{
partial class Form1
{
    /// <summary>
    /// Required designer variable.
    /// </summary>
    private System.ComponentModel.IContainer components = null;

    /// <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);
    }

    #region Windows Form Designer generated code

    /// <summary>
    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>
    private void InitializeComponent()
    {
        this.components = new System.ComponentModel.Container();
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.Text = "Form1";
    }

    #endregion
}
}

我认为这是因为你的命名空间不一样造成的。由于设计器生成的部分代码不继承自 Form,因此您没有方法可以重写。一旦你通过匹配命名空间使两个 类 正确地结合在一起,它应该可以工作。

要修复它,您可以更改设计器代码的命名空间以匹配您的 Form1 命名空间:

namespace Form1
{
    partial class Form1
    {
        //...
    }
}

或更改您的表单以匹配设计师:

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        //....
    }
}

编辑项目属性并更新默认命名空间以匹配所有表单所需的命名空间
