MethodInfo methodInfo = type.GetMethod(methodname, BindingFlags.Public | BindingFlags.IgnoreCase|BindingFlags.Instance);//BindingFlags.IgnoreCase  不区分大小写

BindingFlags flag = BindingFlags.Public | BindingFlags.IgnoreCase | BindingFlags.Instance;
Type type = instance.GetType();
PropertyInfo CreateDate = type.GetProperty("CreateDate", flag);
if (CreateDate != null)
{
CreateDate.SetValue(instance, DateTime.Now, null); //创建时间
}

之前没有红色背景的参数，加上这个就ok了

c# type.GetProperty 如何不让区分大小写
