问题描述

你好



我有以下情况：我有一个WCF网络服务，其中包含枚举。我有另一个应用程序（一个网站），我在其中调用Web服务并使用Web服务中的枚举来创建下拉列表。当我在localhost上运行网站时，一切都很好。但是在我在Web服务器上部署我的解决方案之后，我使用枚举生成的下拉列表被混淆了（枚举的值以另一个顺序显示）。欢迎任何形式的帮助。



查找下面的代码示例：



1.使用的枚举

Hello

I have the following situation: I have a WCF web service which contains, among others, enums. I have another application (a web site), in which I call the web service and use the enums from the web service to create dropdown lists. When I run the web site on localhost, everything is fine. But after I deploy my solutions on a web server, my dropdown lists generated with enums are mixed up (the values of the enum are shown in another order). Any kind of help is welcome.

Find below a code example:

1. An enum used

[System.Runtime.Serialization.DataContract(Namespace = Cfg.MtplSchemaNamespace)]
    public enum MtplLegalEntityEnum : int
    {
        [System.Runtime.Serialization.EnumMember]
        PhysicalPerson = 1,
        [System.Runtime.Serialization.EnumMember]
        JuridicalPerson = 2,
        [System.Runtime.Serialization.EnumMember]
        SelfEmployed = 3
    }

2.我用来从我的枚举中生成下拉列表的函数：

2. The functions I use to generate dropdown lists from my enums:

public void InitDropDownList(DropDownList dropDownList, Type enumerator)
    {
        Hashtable ht = GetEnumForBind(enumerator);
        dropDownList.DataSource = ht;
        dropDownList.DataTextField = "value";
        dropDownList.DataValueField = "key";
        dropDownList.DataBind();
    }

private Hashtable GetEnumForBind(Type enumeration)
    {
        string[] names = Enum.GetNames(enumeration);
        Array values = Enum.GetValues(enumeration);
        Hashtable ht = new Hashtable();

        for (int i = 0; i < names.Length; i++)
        {
            // Get the global resource string.
                try
                {
                    // Look in the global resource file called MyResource.resx.
                    string resKey = enumeration.Name + "_" + names[i];

                    if ((String)GetGlobalResourceObject("enums", resKey) == null) throw new Exception("Could not find global resource.");
                    ht.Add(Convert.ToInt32(values.GetValue(i)).ToString(), (String)GetGlobalResourceObject("enums", resKey));
                }
                catch
                {
                    ht.Add(Convert.ToInt32(values.GetValue(i)).ToString(), names[i]);
                }
        }
        return ht;
    }

3.函数的调用：

3. The call of the function:

InitDropDownList(ddlPersonType, typeof(Sk.Mtpl.MtplLegalEntityEnum));

提前谢谢。

Thank you in advance.

推荐答案

请参阅我对该问题的评论。使用枚举类型是高效和健壮的，但是...枚举成员，它们的值和顺序存在一些非平凡的问题。我在文章中描述了这些问题的详细程度：

枚举类型不能枚举！解决.NET和语言限制 [ ^ ]。



即使您在问题中提供的信息远远不够，也许您将能够在阅读了我对枚举问题的解释之后解决了这个问题。



再次，如果你提供更多信息，也许我将能够找出你的问题并建议解决方案。

Please see my comment to the question. Using enumeration types is highly productive and robust, but… There are some non-trivial issues with the enumeration members, their values and order. I describe these problem is good level of detail in my article:
Enumeration Types do not Enumerate! Working around .NET and Language Limitations[^].

Even though the information you provided in your question is by far insufficient, perhaps you will be able to sort things out after reading of my explanation of the enumeration issues.

Again, if you provide more information, maybe I will be able to identify your problem and suggest the resolution.

我发现了问题。该问题由InitDropDownList函数生成。谢谢你的建议Sergey Alexandrovich。



祝你好运，

Mihai。

I have found the problem. The issue was generated by the InitDropDownList function. Thank you for your suggestions Sergey Alexandrovich.

Best regards,
Mihai.
