我在反序列化期间得到一个异常

我在运行以下代码时收到此消息:

XML文档(6,22)中存在错误。

namespace N1
{
    public class InputEntry
    {
        //FieldName is a class tht is generated from an XSD which has complex type Name and value
        private Field fields;
        public Field[] Fields
        {
            get { return this.fields; }
            set { this.fields= value; }
        }

        public string FieldName
        {
           get{return this.fieldName;}
           set { this.fieldName = value; }
        }

            serializer.Serialize(inputStr, inputEntry);
            string ipEntry = inputStr.ToString();

    }
}
     // when client configues input data as
