在c#中将控件和变量的状态从一个窗体复制到另一个窗体
本文关键字:窗体 一个 复制 另一个 控件 状态 变量 | 更新日期: 2023-09-27 17:58:02
我有一个windows窗体。如果用户没有选中复选框,稍后按next时会打开一个新窗体,但如果用户选中了它,则会使用相同的窗体
如果他们选中复选框,我希望显示当前表单的克隆(具有相同的变量和控制值),这样他们以后就可以更改值,而无需取消选中复选框、再次按"下一步"并手动键入其他值
CCD_ 1只是引用了相同的形式,不存在CCD_
我无法尝试Form duplicate = new Form() = this
,因为我的表单采用了早期表单中的构造函数
有人知道怎么做吗?提前感谢
您可以在表单中添加以下方法:
public void RestoreState(Dictionary<string, object> controlStates,
Dictionary<string, object> membersStates)
{
InternalRestoreControls(controlStates);
InternalRestoreMembers(membersStates);
}
private void InternalRestoreControls(Dictionary<string, object> states)
{
foreach (var state in states)
{
Control c = this.Controls.Find(state.Key, true).FirstOrDefault();
if (c is TextBox)
{
(c as TextBox).Text = state.Value == null ? null : state.Value.ToString();
}
else if (c is CheckBox)
{
(c as CheckBox).Checked = Convert.ToBoolean(state.Value);
}
}
}
private void InternalRestoreMembers(Dictionary<string, object> membersStates)
{
// you might need to tweek this a little bit based on public/instance/static/private
// but this is not the point of your question
BindingFlags flags = BindingFlags.Instance | BindingFlags.Static
| BindingFlags.Public | BindingFlags.NonPublic;
var props = this.GetType().GetProperties(flags);
var fields = this.GetType().GetFields(flags);
foreach(var variable in membersStates)
{
var prop = props.FirstOrDefault(x => x.Name == variable.Key);
if(prop != null)
{
prop.SetValue(this, variable.Value);
continue;
}
var field = fields.FirstOrDefault(x => x.Name == variable.Key);
if(field != null)
{
field.SetValue(this, variable.Value);
continue;
}
}
}
private Dictionary<string, object> GetControlsState()
{
return new Dictionary<string, object>()
{
{ txtBox1.Name, txtBox1.Text },
// continue to the rest
};
}
private Dictionary<string, object> GetMembersState()
{
return new Dictionary<string, object>()
{
{ nameof(variable1), variable1 },
// continue to the rest
};
}
用法:
Form duplicate = new Form();
duplicate.RestoreState(this.GetControlsState(), this.GetMembersState());
以下是我要做的:让我们假设你想用一个按钮打开"克隆"。以到克隆的形式:
public Form1()
{
InitializeComponent();
}
public Form1(string YourValue, int AnotherValue) //This basically works like a constructor when the form is called
{
InitializeComponent();
ValueLabel1.Text = YourValue;
ValueLabel2.Text = Convert.ToString(AnotherValue);
}
private void DuplicateButton_Click(object sender, EventArgs e)
{
int a = 3;
Form1 Window = new Form1(TextBox1.Text, a);
Window.Show;
}
我希望这对你有效
您可以使用一个以控件名称为键、以控件值为值的字典,并将其作为可选参数传递
public form1(string para1, int para2, Dictionary<string,object>yourDic=null)
{
}
