Answer 1

看看窗体的Form1 .Designer.cs文件
命名空间,类名是不是和.cs里一致

Answer 2

还是不行
Form1 .Designer.cs文件：
namespace WindowsFormsApplication9
{
    public  partial class Form1
    {
        /// <summary>
        /// 必需的设计器变量。
        /// </summary>
        private System.ComponentModel.IContainer components = null;        /// <summary>
        /// 清理所有正在使用的资源。
        /// </summary>
        /// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }        #region Windows 窗体设计器生成的代码        /// <summary>
        /// 设计器支持所需的方法 - 不要
        /// 使用代码编辑器修改此方法的内容。
        /// </summary>
        private void InitializeComponent()
        {
            this.SuspendLayout();
            // 
            // Form1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(284, 262);
            this.Name = "Form1";
            this.Text = "Form1";
            this.Load += new System.EventHandler(this.Form1_Load);
            this.ResumeLayout(false);        }        #endregion
    }
}

Answer 3

一开始就叫你检查命名空间了
Form1.cs的命名空间是:namespace mycomserialport
Form1.Designer.cs的命名空间是:namespace WindowsFormsApplication9
修改成一致就行
