第一种方法:
用委托,Form2和Form3是同一组
Form2
usingSystem;
usingSystem.Collections.Generic;
ponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Text;
usingSystem.Windows.Forms;
namespaceTestMouseMove
{
publicdelegatevoidSetVisiableHandler();
publicpartialclassForm2:Form
{
publicForm2()
{
InitializeComponent();
}
privatevoidbutton1_Click(objectsender,EventArgse)
{
Form3frm=newForm3(newSetVisiableHandler(SetVisiable));
frm.Show();
}
privatevoidSetVisiable()
{
SetVisiable(this.label1,!this.label1.Visible);
}
privatevoidSetVisiable(Controlcontrol,boolvisiable)
{
if(this.Controls.Contains(control))
{
control.Visible=visiable;
}
}
}
}
Form3
usingSystem;
usingSystem.Collections.Generic;
ponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Text;
usingSystem.Windows.Forms;
namespaceTestMouseMove
{
publicpartialclassForm3:Form
{
privateSetVisiableHandlerm_setVisible;
publicForm3(SetVisiableHandlersetvisible)
{
InitializeComponent();
this.m_setVisible=setvisible;
}
privatevoidbtnVisible_Click(objectsender,EventArgse)
{
if(this.m_setVisible!=null)
{
this.m_setVisible();
}
}
}
}
第二种方法:
用变量,Form4和Form5是同一组
Form4
usingSystem;
usingSystem.Collections.Generic;
ponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Text;
usingSystem.Windows.Forms;
namespaceTestMouseMove
{
publicpartialclassForm4:Form
{
publicForm4()
{
InitializeComponent();
}
#region子窗口刷新父窗口的值
privatestringstrLabel1="";
publicstringStrLabel1
{
get
{
returnstrLabel1;
}
set
{
strLabel1=value;
this.label1.Text=strLabel1;
}
}
#endregion
privatevoidbutton1_Click(objectsender,EventArgse)
{
Form5form5=newForm5(this);//这里注意传个this
form5.Show();
}
}
}
usingSystem;
usingSystem.Collections.Generic;
ponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Text;
usingSystem.Windows.Forms;
namespaceTestMouseMove
{
publicpartialclassForm4:Form
{
publicForm4()
{
InitializeComponent();
}
#region子窗口刷新父窗口的值
privatestringstrLabel1="";
publicstringStrLabel1
{
get
{
returnstrLabel1;
}
set
{
strLabel1=value;
this.label1.Text=strLabel1;
}
}
#endregion
privatevoidbutton1_Click(objectsender,EventArgse)
{
Form5form5=newForm5(this);//这里注意传个this
form5.Show();
}
}
}
Form5
usingSystem;
usingSystem.Collections.Generic;
ponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Text;
usingSystem.Windows.Forms;
namespaceTestMouseMove
{
publicpartialclassForm5:Form
{
Form4form4=newForm4();
publicForm5(Form4formFrm)//这个构造方法里有参数
{
form4=formFrm;//这个必须要有
InitializeComponent();
}
privatevoidbutton1_Click(objectsender,EventArgse)
{
form4.StrLabel1=this.textBox1.Text;
}
}
}
