坐等回复：C#跨窗体操作控件，求详细代码改错

C# code

窗口1 的代码namespace HistoryGame{    public delegate void CloseForm();      public partial class FrmSuspend : Form    {                public FrmSuspend()        {            InitializeComponent();        }        public event CloseForm FrmSuspendClose;          public void picContinue_Click(object sender, EventArgs e)        {            FrmSuspendClose();        }窗体2namespace HistoryGame{    public partial class FrmSuspendCopy : Form    {        public FrmSuspendCopy()        {            InitializeComponent();        }        FrmSuspend frc = new FrmSuspend();        void CloseBySuspend(bool topmost)        {            this.DialogResult = DialogResult.OK;            this.Close();        }        private void FrmSuspendCopy_Load(object sender, EventArgs e)        {        }        private void pictureBox1_Click(object sender, EventArgs e)        {            frc.FrmSuspendClose += new CloseForm(CloseBySuspend);        }    }}为什么窗体1单击后出现 FrmSuspendClose(); 未进行实例化。的错误，请问什么情况。

我要实现的效果是从窗口1的按钮单击后调用窗体2（CloseBySuspend）的方法，请问有没有更好的方案，求方案。

[解决办法]
可以直接实例化调用就行了
public void picContinue_Click(object sender, EventArgs e)
{
FrmSuspendCopy frm2=new FrmSuspendCopy();
frm2.CloseBySuspend(true);
}
[解决办法]
你那2个窗体看起来没任何关联


你上面的代码2个窗体还没关联，虽然在FrmSuspendCopy中实例了FrmSuspend窗体，但是没有加载
frc.FrmSuspendClose += new CloseForm(CloseBySuspend);

C# code

namespace HistoryGame{    public partial class FrmSuspendCopy : Form    {        public FrmSuspendCopy()        {            InitializeComponent();        }        FrmSuspend frc = new FrmSuspend();        void CloseBySuspend(bool topmost)        {            this.DialogResult = DialogResult.OK;            this.Close();        }        private void FrmSuspendCopy_Load(object sender, EventArgs e)        {          frc.FrmSuspendClose += new CloseForm(CloseBySuspend);        }        private void pictureBox1_Click(object sender, EventArgs e)        {                 }    }}

窗体 1中  FrmSuspendClose () 实例在哪?  //就是这个frc.FrmSuspendClose += new CloseForm(CloseBySuspend);

       void CloseBySuspend(bool topmost)
       {
           this.DialogResult = DialogResult.OK;
           this.Close();
       }
这个改成 public  然后在 窗体1中 绑定到 FrmSuspendClose 上
