传递到字典中的模型项的类型为'System.Data.Entity.DynamicProxies...‘，并且需要类型为

public Dictionary<string, object> ConvertModelToDictionary(object model)
{
    Dictionary<string, object> dictionary = new Dictionary<string, object>();
    PropertyInfo[] properties = model.GetType().GetProperties();

    foreach (PropertyInfo property in properties)
    {
        object value = property.GetValue(model);

        if (value != null)
        {
            if (IsDynamicProxyType(value.GetType()))
            {
                // 如果属性值的类型为'System.Data.Entity.DynamicProxies...'，则递归地将其转换为字典
                dictionary[property.Name] = ConvertModelToDictionary(value);
            }
            else
            {
                dictionary[property.Name] = value;
            }
        }
    }

    return dictionary;
}

public bool IsDynamicProxyType(Type type)
{
    // 判断类型是否为'System.Data.Entity.DynamicProxies...'
    return type.FullName.StartsWith("System.Data.Entity.DynamicProxies");
}

// 创建一个类型为'System.Data.Entity.DynamicProxies...'的模型项
var model = new System.Data.Entity.DynamicProxies.ModelItem();

// 将模型项转换为字典
var dictionary = ConvertModelToDictionary(model);

// 打印字典内容
foreach (var kvp in dictionary)
{
    Console.WriteLine($"{kvp.Key}: {kvp.Value}");
}
