1.将主程序界面上的Icon赋给基类内的Icon(同时其他子类也具有了此Icon):

public partial class BaseForm : Form
{
    public BaseForm()
    {
        InitializeComponent();
 
        String exeFileName = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + "\\A.B.Main.exe";
        if (System.IO.File.Exists(exeFileName))
        {
            System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFrom(exeFileName);
            if (assembly != null)
            {
                System.IO.Stream stream = assembly.GetManifestResourceStream("A.B.Main.C.ico");
                if (stream != null)
                {
                    this.Icon = new Icon(stream);
                }
            }
        }
    }
}

2、获取接口：

Assembly assembly = Assembly.LoadFrom(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + "\\A.B.UI.dll");
           this.iUIC = assembly.CreateInstance("A.B.UI.UIC", false, BindingFlags.Default, null, null, null, null) as IUIC;

3、获取xml文件

Assembly assembly = Assembly.LoadFrom(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + "\\A.B.UI.dll");
           Stream stream = assembly.GetManifestResourceStream(assembly.GetName().Name + ".Config.xml");
           System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
           xmlDoc.Load(stream);
           stream.Close();
           stream.Dispose();

4、创建窗体：

public static Form CreateForm(String formAssemblyFile, String formFullName, Object[] formArgs, String formName, String formText)
       {
           Form form;
           Assembly formAssembly = Assembly.LoadFrom(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + "\\" + formAssemblyFile);
 
           if (formArgs == null)
           {
               form = formAssembly.CreateInstance(formFullName, false, BindingFlags.Default, null, null, null, null) as Form;
           }
           else
           {
               form = formAssembly.CreateInstance(formFullName, false, BindingFlags.Default, null, formArgs, null, null) as Form;
           }
 
           if (form == null)
           {
               string strError = string.Format("CreateForm失败\nformAssemblyFile={0}\nformFullName={1}\nformName={2}\nformText={3}",
                   formAssemblyFile,
                   formFullName,
                   formName,
                   formText);
               throw new Exception(strError);
           }
 
           if (!String.IsNullOrEmpty(formName))
           {
               form.Name = formName;
           }
           if (!String.IsNullOrEmpty(formText))
           {
               form.Text = formText;
           }
 
           return form;
       }

4、获取版本信息：

（1）Assembly.GetExecutingAssembly().GetName().Version.ToString();

（2）object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyDescriptionAttribute), false);
                if (attributes.Length == 0)
                {
                    return "";
                }
                return ((AssemblyDescriptionAttribute)attributes[0]).Description;

（3）object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyProductAttribute), false);
                if (attributes.Length == 0)
                {
                    return "";
                }
                return ((AssemblyProductAttribute)attributes[0]).Product;

反射对控件的操作：调用函数（含参数|不含参数）

#region 调用控件方法
   private void InvokeMethod(String methodName, Control control, Object[] args)
   {
       this.SetPropertyValue("UserTempFilePath", control, this.userTempPathFullName);
 
       try
       {
           Type ctlType = control.GetType();
           MethodInfo mi = null;
           if (args == null)
           {
               mi = ctlType.GetMethod(methodName, System.Type.EmptyTypes);
           }
           else
           {
               mi = ctlType.GetMethod(methodName);
           }
 
           if (mi != null)
           {
               mi.Invoke(control, args);
 
               this.SetPropertyValue("IsReadOnly", control, true);
           }
       }
       catch (Exception e)
       {
           throw e;
       }
   }
   #endregion
 
   #region 设置控件属性
   private void SetPropertyValue(String propertyName, Control control, Object propertyValue)
   {
       Type ctlType = control.GetType();
       PropertyInfo pi = ctlType.GetProperty(propertyName);
       if (pi != null)
       {
           pi.SetValue(control, propertyValue, null);
       }
   }
   #endregion
