fmtjjh1窗口是在项目中重新添加的。
namespace test
{
partial class fmtjjh1
{
/// <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();
你只重命名了文件名,命名空间还需要你手动修改的
检查一下fmtjjh1.designer.cs文件中的namespace
如上所说的 然后在重新生成项目和解决方案
