c# XmlSerializer实例化有错误提示

XmlSerializer lizer = new XmlSerializer(typeof(MyType));

debug提示： System.IO.FileNotFoundException:“Could not load file or assembly ’*.XmlSerializers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null, processorArchitecture=MSIL’. 系统找不到指定的文件。”

改为： XmlSerializer lizer = XmlSerializer.FromTypes(new[] { typeof(MyType) })[0];
