C# 对象间的 深拷贝 实现

    以下的这个类实现了 2个含有部分字段名字相同 的对象的 赋值拷贝。

public class ShallowCopyHelper

    {

        public static void CopyPropertiesValue(object objFrom, object objTo)

        {

            if (null == objFrom)

            {

                return;

            }

            if (null == objTo)

            {

                return;

            }

            Type typeFrom = objFrom.GetType();

            Type typeTo = objTo.GetType();

            if (objFrom is IList)

            {

                try

                {

                    int count = (objFrom as IList).Count;

                    for (int i = 0; i < count; i++)

                    {

                        CopyPropertiesValue((objFrom as IList)[i], (objTo as IList)[i]);

                    }

                }

                catch

                {

                    //

                }

            }

            else

            {

                foreach (System.Reflection.PropertyInfo pi in

                    typeFrom.GetProperties(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance))

                {

                    try

                    {

                        object valueFrom = typeFrom.GetProperty(pi.Name).GetValue(objFrom, null);

                        object valueTo = typeTo.GetProperty(pi.Name).GetValue(objTo, null);

                        if (typeFrom.GetProperty(pi.Name).PropertyType.IsClass

                            && !typeFrom.GetProperty(pi.Name).PropertyType.IsPrimitive

                            && !(valueFrom is String))

                        {

                            CopyPropertiesValue(valueFrom, valueTo);

                        }

                        else

                        {

                            if (valueFrom == null || !valueFrom.Equals(valueTo))

                            {

                                //Set value to latest data

                                typeTo.GetProperty(pi.Name).SetValue(objTo, valueFrom, null);

                            }

                        }

                    }

                    catch

                    {

                        //

                    }

                }

            }

        }

    }
