如何从 C# Web 服务生成 WSDL 文件

Question

我创建了一个像这样的 WebService：

[WebService(Namespace = "http://ns")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class GroupManagerService : WebService
{
    public GroupManagerService()
    {
    }

    [WebMethod]
    public bool MyMethod(string loginname, string country)
    {
        // code here...
    }
}

Is it possible to generated a WSDL file for this code withoutconnecting to a running service? 我搜索并找到了有关 SvcUtil.exe & 的信息。 wsdl.exe，但这些仅在从正在运行的 WebService 检索 WSDL 时起作用。

（对于java，有一个名为java2wsdl的工具，c#有等效的工具吗？）

：更新：
此问题的上下文是我想向 SharePoint 添加新的 CustomWebService，该服务应使用 SharePoint 上的 _vti_bin 文件夹中的 WSPBuilder 进行部署。 另请参阅我在 SharePoint.SE 上的帖子。

我想自动生成（使用 msbuild 命令）'MyServicewsdl.aspx' & 'MyServicedisco.wsdl' 必须放置在 _vti_bin 文件夹中。

也许我错过了一些东西？ svcutil.exe 的输出是：

bin\Debug>SvcUtil.exe MyWebService.dll
Microsoft (R) Service Model Metadata Tool
[Microsoft (R) Windows (R) Communication Foundation, Version 3.0.4506.2152]

Generating metadata files...
Warning: No metadata files were generated. No service contracts were exported.
 To export a service, use the /serviceName option. To export data contracts, spe
cify the /dataContractOnly option. This can sometimes occur in certain security
contexts, such as when the assembly is loaded over a UNC network file share. If
this is the case, try copying the assembly into a trusted environment and runnin
g it.

Answer 1

我创建了一个工具，可以从包含一个或多个 Web 服务的已编译 C# 程序集 (dll) 生成 WSDL 文件。
通常，您需要托管 .asmx 的正在运行的服务（IIS 或其他），以便您可以使用 /MyWebService.asmx?wsdl 检索 WSDL。

此工具使用反射生成 WSDL 文件，以从程序集 (dll) 检索所有信息。

请参阅 svcutil /?

                          -= METADATA EXPORT =-

Description: svcutil.exe can export metadata for services, contracts and data types in compiled assemblies. To
    export metadata for a service, you must use the /serviceName option to indicate the service you would like
    to export. To export all Data Contract types within an assembly use the /dataContractOnly option. By
    default metadata is exported for all Service Contracts in the input assemblies.

Syntax: svcutil.exe [/t:metadata] [/serviceName:<serviceConfigName>] [/dataContractOnly] <assemblyPath>*

 <assemblyPath> - The path to an assembly that contains services, contracts or Data Contract types to be
                  exported. Standard command-line wildcards can be used to provide multiple files as input.

Options:

 /serviceName:<serviceConfigName> - The config name of a service to export. If this option is used, an
                                    executable assembly with an associated config file must be passed as
                                    input. Svcutil will search through all associated config files for the
                                    service configuration. If the config files contain any extension types,
                                    the assemblies containing these types must either be in the GAC or
                                    explicitly provided using the /r option.
 /reference:<file path>           - Add the specified assembly to the set of assemblies used for resolving
                                    type references. If you are exporting or validating a service that uses
                                    3rd-party extensions (Behaviors, Bindings and BindingElements) registered
                                    in config use this option to locate extension assemblies that are not in
                                    the GAC.  (Short Form: /r)
 /dataContractOnly                - Operate on Data Contract types only. Service Contracts will not be
                                    processed. (Short Form: /dconly)
 /excludeType:<type>              - The fully-qualified or assembly-qualified name of a type to exclude from
                                    export. This option can be used when exporting metadata for a service or a
                                    set of service contracts to exclude types from being exported. This option
                                    cannot be used with the /dconly option. (Short Form: /et)

Answer 3

Svcutil.exe 肯定会在服务关闭时生成 WSDL。正确的用法是 svcutil your.executable.dll(exe)。
我经常使用它，所以我确信它会生成 WSDL。
