这个C#代码提供了一些实用的静态方法，用于检查和操作窗体（Form）。包括检查窗体是否已打开、获取指定名称的窗体、在Panel中显示窗体、处理DataGridView列的显示、获取操作类型名以及加载ComboBox仓库数据。这些方法可以方便地在Windows应用中增强用户界面的交互和管理。

public static class FormUtility
{
    //静态类中的静态方法---扩展方法

    //检查一个Form是否已打开
    public static bool CheckOpenForm(string frmName)
    {
        bool bl = false;
        foreach (Form f in Application.OpenForms)
        {
            if (f.Name == frmName)
            {
                bl = true;
                break;
            }
        }
        return bl;
    }

    //获取指定Name的Form
    public static Form GetOpenForm(string frmName)
    {
        Form frm = null;
        foreach (Form f in Application.OpenForms)
        {
            if (f.Name == frmName)
            {
                frm = f;

            }
