根据typeName获取Type较为完备的办法

 前年还在开发.NET产品，我那时候编写一个C#脚本解释引擎，遇到一个问题是，Type.GetType()方法无法获取尚未装载类型。这些天，在阅读一些相关的代码时，得知了一种较为完整的方法，共享如下：

internal static Type FindTypeInCurrentDomain(string typeName) {      Type type = null;        //如果该类型已经装载      type = Type.GetType(typeName);      if (type != null)      {           return type;      }      //在EntryAssembly中查找      if (Assembly.GetEntryAssembly() != null)      {           type = Assembly.GetEntryAssembly().GetType(typeName);           if (type != null)           {                return type;           }      }      //在CurrentDomain的所有Assembly中查找      Assembly[] assemblyArray = AppDomain.CurrentDomain.GetAssemblies();      int assemblyArrayLength = assemblyArray.Length;      for (int i = 0; i < assemblyArrayLength; ++i)      {           type = assemblyArray[i].GetType(typeName);           if (type != null)           {                return type;           }      }      for (int i = 0; (i < assemblyArrayLength); ++i)      {           Type[] typeArray = assemblyArray[i].GetTypes();           int typeArrayLength = typeArray.Length;           for (int j = 0; j < typeArrayLength; ++j)           {                if (typeArray[j].Name.Equals(typeName))                {                     return typeArray[j];                }           }      }      return type; }
