例如如下string类型的x'm'l格式字符串，
string xmltest="<?xml version="1.0" encoding="utf-8"?><Data>
<properties name="ProductID">123</properties>
<properties name="UserName">usernmva</properties>
<properties name="Password">123</properties>
<properties name="Number">432</properties>
<properties name="TableID">321</properties>
<properties name="Stage">123</properties>
<properties name="Inning"></properties>
<properties name="NameID"></properties>
<properties name="Kind"></properties>
<properties name="Content"></properties>
<properties name="ResultType"></properties>
<properties name="Amount"></properties>
<properties name="Rate"></properties>
<properties name="Balance"></properties>
<properties name="AddTime"></properties>
</Data>";

我使用xml解析的方式解析
public static T get<T>(T tModel)
{

        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.LoadXml(xmltest);
        XmlElement element = xmlDoc.DocumentElement;
        T objModel = Activator.CreateInstance<T>();
        foreach (XmlNode childNode in element.ChildNodes)
        {
            var attr = childNode.Attributes;
            if (attr != null)
            {
                for (int i = 0; i < attr.Count; i++)
                {
                    PropertyInfo info = objModel.GetType().GetProperty(attr[i].Value);
                    if (info == null) continue;
                    info.SetValue(objModel, childNode.InnerXml, null);
                }
            }
            else
            {
                XmlNodeList xmlList = xmlDoc.ChildNodes;
                foreach (XmlNode item in xmlList)
                {
                    PropertyInfo pi = objModel.GetType().GetProperty(item.Name);
                    if (pi == null) continue;
                    if (!string.IsNullOrEmpty(item.InnerXml.Trim()))
                        pi.SetValue(objModel, item.InnerXml, null);
                }
            }
        }
        return objModel;
    }

在第一个循环中，给 info.SetValue(objModel, childNode.InnerXml, null);chidNode.InnerXml是string 类型的，在ObjModel中类型不一直，转换失败，有什么办法能在赋值的时候类型保持一致呢？
