--------------------编程问答-------------------- 看看窗体的Form1 .Designer.cs文件
命名空间,类名是不是和.cs里一致
--------------------编程问答-------------------- 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
}
}
--------------------编程问答-------------------- 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
补充：.NET技术 , C#
