我正在开发一个Windows应用程序,并创建了一个用于设置CommonAppearance类代码的
通用外观类
static void SetCommonAppearance(Label ctrl){ //some appearance setting code}
static void SetCommonAppearance(GridGroupingControl ctrl){ //some appearance setting code}
static void SetCommonAppearance(GradientPanel ctrl){ //some appearance setting code}
static void SetCommonAppearance(Form ctrl){ //some appearance setting code}
static void SetCommonAppearance(ComboBox ctrl){ //some appearance setting code}
static void SetCommonAppearance(CheckBox ctrl){ //some appearance setting code}
static void SetCommonAppearance(RadioButton ctrl){ //some appearance setting code}
static void SetCommonAppearance(Button ctrl){ //some appearance setting code}
public static void UseCommonTheme(Form form)
{
List<Control> lstControls = GetAllControls(form.Controls);
foreach (Control ctr in lstControls)
{
string temp2 = ctr.GetType().Name;
switch (temp2)
{
case "TextBox":
SetCommonAppearance((TextBox)ctr);
break;
case "AutoLabel":
SetCommonAppearance((Label)ctr);
break;
case "GridGroupingControl":
SetCommonAppearance((GridGroupingControl)ctr);
break;
case "ButtonAdv":
ApplyCustomTheme((ButtonAdv)ctr);
break;
case "CheckBoxAdv":
SetCommonAppearance((CheckBox)ctr);
break;
case "ComboBoxAdv":
SetCommonAppearance((ComboBox)ctr);
break;
case "RadioButtonAdv":
SetCommonAppearance((RadioButton)ctr);
break;
}
}
}
当设置常见外观的控件应用程序较少时,这是可以接受的,但在我的应用程序中使用了许多不同类型的控件。
在方法中UseCommonTheme(Form form)
而不是使用开关大小写 我们可以使用反射来投射控件吗? 类似
的东西
foreach (Control ctr in lstControls)
{
string controlType = ctr.GetType().Name;
SetCommonAppearance((class reference of 'controlType')ctr);
}
提前谢谢。
如果您使用的是 .net 4,则可以利用 dlr(动态语言运行时):
foreach (dynamic ctr in lstControls)
{
SetCommonAppearance(ctr);
}
dlr 将为您解决正确的重载问题。
如果要使用反射:
var type = typeof(CommonAppearance);
var methods = type.GetMethods(BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public);
foreach (Control ctr in lstControls)
{
var setAppearanceMethod =
methods.FirstOrDefault(m => m.GetParameters()[0].ParameterType == ctr.GetType());
if(setAppearanceMethod!=null)
setAppearanceMethod.Invoke(null, new[] { ctr });
}
