before B is closed:
在 B 关闭之前：
C.MdiParent = B.MdiParent; // which is pointing to A

In Form B button click where you are calling Form C, you have to assign the MdiParent of FormB to MdiParent of FormC which is FormA. After that you can close FormB.
在 Form B 按钮单击您调用 Form C 的位置，您必须将 FormB 的 MdiParent 分配给 FormC 的 MdiParent，即 FormA。之后，您可以关闭 FormB。
//FormB Button Click
//FormB按钮点击
private void button1_Click(object sender, EventArgs e)
{
FormC frm = new FormC();
frm.MdiParent = this.MdiParent; // assign MdiParent of FormB to FormC
frm.Show();
this.Close();
}
