在WebForm中，可以使用反射將業務對象綁定到 ASP.NET 窗體控件。最近做Winform項目，也參考WebForm中的代碼實現同樣的功能。DevExpress XtraReports下載

Winform沒有提供類似WebForm控件中的FindControl方法，我于是用遍歷控件的方式，寫了一個類似WebForm中的這個方法，考慮到Winform中的很多控件放在Label、TabControl中，方法采用了遞歸的方式。

Winform和Winform的控件也有些區別，如在Winform中，DateTimePicker取值是用Value屬性，在WebForm中使用SelectDate屬性，在Winform中，有NumericUpDown控件，取值也是用Value屬性，因此，具體綁定方式上也和WebForm中有些區別。

////代碼如下：

using System.Windows.Forms;
using System.Reflection;
using System.Collections;
namespace BindTest
{
public sealed class FormBinding
{
/// <summary>

{
if (obj == null) return;
Type objType = obj.GetType();
PropertyInfo[] objPropertiesArray = objType.GetProperties();
foreach (PropertyInfo objProperty in objPropertiesArray)
{
Control control = FindControl(container, objProperty.Name);
if (control == null) continue;
if (control is DateTimePicker)
{
DateTimePicker dateTimePicker = (DateTimePicker)control;
dateTimePicker.Value = (DateTime)objProperty.GetValue(obj, null);
}
else
{
//獲取控件的屬性
Type controlType = control.GetType();
PropertyInfo[] controlPropertiesArray = controlType.GetProperties();
//通用屬性

public class Model

private string test1;

public string Test1
{
set { test1 = value; }
get { return test1; }

public DateTime Test2
{
set { test2 = value; }
get { return test2; }
}
public string Test3
{
set { test3 = value; }
get { return test3; }
}
}

在一個Winform中，放兩個TextBox控件，一個DateTimePicker控件，一個Panel控件，分別命名位Test1、Test2、Test3，其中把Text3控件放在Panel1中。

將業務對象綁定到窗體：

Model model = new Model();
model.Test1 = "Hello,World!";
model.Test2 = DateTime.Now.AddMonths(-2);
model.Test3 = "Nice to meet u!";
FormBinding.BindObjectToControls(model, this);

將窗體綁定到業務對象：

Model model = new Model();
FormBinding.BindControlsToObject(model, this);
MessageBox.Show(model.Test1 + " " + model.Test2.ToShortDateString() + " " + model.Test3);
