所以,我有一个使用索引属性的类对象。我遍历对象的属性,但我想跳过索引属性本身。
除了检查属性名称是否为“Item”之外,索引属性的默认值还有另一种方法来检查此属性以跳过它吗?
这是我的代码:
具有 index 属性的类。
public class MyClass{
//Index Property
public object this[string propertyName]
{
get
{
return PropertyHelper.GetPropValue(this, propertyName);
}
set
{
if (PropertyHelper.GetPropType(this, propertyName) == typeof(Guid?))
{
PropertyHelper.SetPropValue(this, propertyName, Guid.Parse(value.ToString()));
}
else if (PropertyHelper.GetPropType(this, propertyName) == typeof(int))
{
PropertyHelper.SetPropValue(this, propertyName, int.Parse(value.ToString()));
}
else if (PropertyHelper.GetPropType(this, propertyName) == typeof(string))
{
PropertyHelper.SetPropValue(this, propertyName,value.ToString());
}
}
public Guid? Id { get; set; }
public int empId { get; set; }
public string morePropertiesLikeThis {get;set;}
}
//PropertyHelper 类
public static class PropertyHelper
{
public static object GetPropValue(object src, string propName)
{
return src.GetType().GetProperty(propName).GetValue(src, null);
}
public static Type GetPropType(object src, string propName)
{
return src.GetType().GetProperty(propName).PropertyType;
}
public static void SetPropValue(object src, string propName, object value)
{
src.GetType().GetProperty(propName).SetValue(src, value, null);
}
}
用法:
//Build Query String
string parameters = "?";
int r = 1;
foreach (PropertyInfo info in typeof (MyClass).GetProperties())
{
//I want to use some less prone to change, than text Item
if (info.Name == "Item")
{
continue;
}
var property = PropertyHelper.GetPropValue(conditions, info.Name);
if (property != null)
{
if (r > 1)
{
parameters += "&" + info.Name + "=" +
conditions.GetType().GetProperty(info.Name).GetValue(conditions, null);
}
else
{
parameters += info.Name + "=" +
conditions.GetType().GetProperty(info.Name).GetValue(conditions, null);
}
r++;
}
}
