如何投射對象在C＃中使用反射運行時？

Question

我正在開發一個Windows應用程序，並在我創造了共同的外觀一類和感應設置

CommonAppearance類代碼：

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; 
     } 

    } 
} 

當有較少的控制應用程序設置的共同出現，但在這是可以接受的我的應用程序中使用了多種不同類型的控件。
在方法UseCommonTheme(Form form)而不是使用開關的情況下我們可以使用反射來施放控件嗎？財產以後像

foreach (Control ctr in lstControls) 
{ 
    string controlType = ctr.GetType().Name; 
    SetCommonAppearance((class reference of 'controlType')ctr); 
} 

在此先感謝。

如果您使用的是.NET 4，你可以利用DLR（動態語言運行時）的：

foreach (dynamic ctr in lstControls) 
{ 
    SetCommonAppearance(ctr); 
} 

的DLR將解析正確的過載你。

如果你想使用反射：

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 }); 
}
