一般地填入不同的类成员 [英] Generically populate different classes members

问题描述

我的工作与几个（11）的Web服务调用的Web服务应用程序。

I am working on a web-service application with several (11) web-service calls.

对于每一个网络服务，我需要从一个字符串数组这样的填充SOAP体：

For each web-service I need to populate the Soap Body from a string array like this:

if (aMessage[(int)DCSSCustomerUpdate_V3.Branch].ToString().Length != 0)
{
    wsSoapBody.Branch = aMessage[(int)DCSSCustomerUpdate_V3.Branch].ToString();
}

aMessage [INT] 是字符串数组，[INT]是由一个枚举常量定义 - 在这种情况下，它的定义是这样的：

aMessage[int] is the string array, and [int] is defined by an enumerated constant - in this case it is defined like this:

private enum DCSSCustomerUpdate_V3
{
    MsgType = 0,
    MsgVersion = 1,
    WSName = 2,
    ReplyTo = 3,
    SourceSystem = 4,
    ...
}

在部分类属性名称由枚举常数匹配，所以我想我会通过在枚举常量呢？

The property names in the partial class are matched by the enumerated constant, so I guess I'd pass in the enumerated constant as well?

在部分类的是在这样的WSDL定义的：

The partial class is defined in the wsdl like this:

public partial class DCSSCustomerUpdateType 
{
    private string instIdField;
    private string branchField;
    ...
}

而不是每一个单独做这个（每11个自定义的服务的类），我不知道有没有办法通过在部分类的 wsSoapBody （沿以字符串数组）和遍历类的所有成员，从字符串数组赋值？

Rather than doing this for each one separately (in each of 11 custom service classes), I wonder is there a way to pass in the partial class wsSoapBody (along with the string array) and loop through all the members of the class, assigning values from the string array?

修改

我搜查，发现<一href="http://stackoverflow.com/questions/531384/how-to-loop-through-all-the-properties-of-a-class">SO: 531384 /如何对环通全的 - 属性 - 即用A级？

所以，我想这样的：

    public static void DisplayAll(Object obj, string[] aMessage)
    {
        Type type = obj.GetType();
        PropertyInfo[] properties = type.GetProperties();

        foreach (PropertyInfo property in properties)
        {
            string value = aMessage[property.Name].ToString();
            System.Diagnostics.Debug.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(obj, null));
        }
     }

但字符串值= aMessage [property.Name]的ToString（）; 将无法编译 - 因为它是在寻找一个int从列举的常数返回..

but string value = aMessage[property.Name].ToString(); won't compile - as it is looking for an int returned from an enumerated constant...

所以我在哪里从那里去？

so where do I go from there?

推荐答案

尽量让

DCSSCustomerUpdate_V3 t = (DCSSCustomerUpdate_V3)Enum.Parse(typeof(DCSSCustomerUpdate_V3), property.Name);
 string value = aMessage[(int)t].ToString();

您也可以使用方法枚举。的TryParse

有关通用枚举类型的更多或更少，以便

For generic Enum type more or less so

 public static void DisplayAll<TEnum>(Object obj, string[] aMessage) where TEnum : struct,  IComparable, IFormattable, IConvertible
        {
            if (!typeof(TEnum).IsEnum)
            {
                throw new ArgumentException("T must be an enumerated type");
            }

            Type type = obj.GetType();
            PropertyInfo[] properties = type.GetProperties();

            foreach (PropertyInfo property in properties)
            {
                TEnum t = (TEnum)Enum.Parse(typeof(TEnum), property.Name);
                string value = aMessage[t.ToInt32(Thread.CurrentThread.CurrentCulture)].ToString();
                System.Diagnostics.Debug.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(obj, null));
            }
        }
