本文介绍了一种在C#中实现实体类与Dictionary<string, string>相互转换的方法，通过反射机制获取实体类的属性名及值，便于数据交换和处理。
// 设置Dictionary<string, string> 得到实体类的字段名称和值
public static Dictionary<string, string> GetProperties<T>(T t)
{
Dictionary<string, string> ret = new Dictionary<string, string>();
if (t == null)
{
return null;
}
System.Reflection.PropertyInfo[] properties = t.GetType().GetProperties(System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.Public);
if (properties.Length <= 0)
{
return null;
}
foreach (System.Reflection.PropertyInfo item in properties)
{
string name = item.Name; //实体类字段名称
string value = ObjToStr(item.GetValue(t, null)); //该字段的值
if (item.PropertyType.IsValueType || item.PropertyType.Name.StartsWith("String"))
{
ret.Add(name, value); //在此可转换value的类型
}
}
return ret;
}
//反过来根据Dictionary来设置实体类
public static T SetProperties<T>(T t, Dictionary<string, string> d)
{
if (t == null || d == null)
{
return default(T);
}
System.Reflection.PropertyInfo[] properties = t.GetType().GetProperties(System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.Public);
if (properties.Length <= 0)
{
return default(T);
}
foreach (System.Reflection.PropertyInfo item in properties)
{
string name = item.Name; //名称
string value = ObjToStr(item.GetValue(t, null)); //值
if (item.PropertyType.IsValueType || item.PropertyType.Name.StartsWith("String"))
{
string val = d.Where(c => c.Key == name).FirstOrDefault().Value;
if (val != null && val != value)
{
if (item.PropertyType.Name.StartsWith("Nullable`1"))
{
item.SetValue(t, ObjToDate(val), null);
}
else
{
item.SetValue(t, val, null);
}
}
}
}
return t;
}
