我正试图生成一个基于表单输入的电子邮件,使用反射使电子邮件更快,希望更好的方式。
遍历Company对象中的嵌套列表,使_body
是Company及其嵌套对象列表(Asn
和Contact
)中所有属性的长输出列表。
当方法接受Company对象时,它遍历Company中的每个属性并检查它是什么类型。我在检查List<>的类型时出错了,我不知道为什么它不在集合中迭代。
我整个上午都在摆弄代码,但似乎没有任何进展。
我哪里错了?
基本模型结构:
public class Company {
public string name {get;set;}
public List<Asn> asns {get;set;}
public List<Contact> contacts {get;set;}
}
public class Asn {
// string/int/bool properties
}
public class Company {
// string/int/bool properties
}
问题方法代码:
public static void SendEmail(Company cm)
{
string _body = "";
string _subject = "ASN Form Request";
Type type = cm.GetType();
Type type2 = cm.asns.GetType();
Type type3 = cm.contacts.GetType();
PropertyInfo[] companyProperties = type.GetProperties();
PropertyInfo[] asnProperties = type2.GetProperties();
PropertyInfo[] contactProperties = type3.GetProperties();
foreach(PropertyInfo property in companyProperties)
{
if (property.PropertyType == typeof(string) || property.PropertyType == typeof(int) || property.PropertyType == typeof(bool))
_body += property.Name + " = " + property.GetValue(cm, null) + Environment.NewLine;
if (property.PropertyType == typeof(List<>)) // not running through the model properties
foreach(PropertyInfo asnproperty in asnProperties)
{
_body += asnproperty.Name + " = " + asnproperty.GetValue(cm, null) + Environment.NewLine;
}
if(property.PropertyType == typeof(List<>)) // not running through the model properties
foreach(PropertyInfo contactproperty in contactProperties)
{
_body += contactproperty.Name + " = " + contactproperty.GetValue(cm, null) + Environment.NewLine;
}
}
}
如果我理解正确的话,您想要输出公司和列表内部属性中的任何属性。
public static void SendEmail(Company cm)
{
string _body = "";
string _subject = "ASN Form Request";
_body = ReflectObject(cm, _body)
}
public static string ReflectObject(object obj, string body)
{
var type = obj.GetType();
var properties = type.GetProperties();
foreach(PropertyInfo property in properties)
{
if (property.PropertyType == typeof(string) || property.PropertyType == typeof(int) || property.PropertyType == typeof(bool))
body += property.Name + " = " + property.GetValue(cm, null) + Environment.NewLine;
if (property.PropertyType == typeof(List<>))
{
var list = property.GetValue(obj, null)
foreach(var item in list)
{
ReflectObject(item, body);
}
}
}
return body;
}
