Question

我创建了一个具有参数var functionUnitConvertDouble = builder.Function("Convert"); functionUnitConvertDouble.Parameter<int>("From"); functionUnitConvertDouble.Parameter<int>("To"); functionUnitConvertDouble.Parameter<double>("Value"); functionUnitConvertDouble.Returns<double[]>();的函数：

[HttpGet]
[ODataRoute("ConvertUom(From={uomIdFrom},To={uomIdTo},Value={value})")]
public IHttpActionResult ConvertUom([FromODataUri] int uomIdFrom, 
    [FromODataUri] int uomIdTo, [FromODataUri] double value)
{
    // Some stuff here
}

这是与之相关的方法：

http://localhost:63911/odata/Convert(From=4,To=2,Value=20)

功能没问题，我可以调用此网址，但效果很好。

http://localhost:63911/odata/Convert(From=4,To=2,Value=20.5)

但是，我的最后一个参数是double，当我尝试传递一个double参数时它不起作用（我得到一个错误信息，如＆＃34;端点不存在＆＃34;），例如：

由于双精度包含点并且IIS处理点很奇怪（如果它是一个字符串作为参数，则将是相同的），请将其添加到您的web.congfig中。

<system.webServer>
    <!--You might have more stuff here-->

    <modules>
      <remove name="UrlRoutingModule-4.0" />
      <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
    </modules>
</system.webServer>
