情况：我有 3 个网络参考（xMap、xLocation、xRoute）xMap 专用于生成地图。xLocation 专门用于定位地点。xRoute 专门用于生成路由。

我正在使用一个简单的 GUI 来显示地图并输入起点和终点路线的位置。

这些是我的错误。

错误 1 ​​无法将类型“Plantool.xRoute.LineString[]”隐式转换为“Plantool.xMap.LineString[]”

错误 2 'Plantool.xMap.XMapWSService.renderMapBoundingBox(Plantool.xMap.BoundingBox, Plantool.xMap.MapParams, Plantool.xMap.ImageInfo, Plantool.xMap.Layer[], bool, Plantool.xMap.CallerContext 的最佳重载方法匹配)' 有一些无效的参数

错误 3 参数“1”：无法从“Plantool.xRoute.BoundingBox”转换为“Plantool.xMap.BoundingBox”

我猜测 PTV xServer 的重复方法/功能/等与 xMap、xLocate、xRoute 是可选模块相同。这可能是一个简单的答案，有解决方案吗？

我正在寻找回家的长途旅行的头，并在此代码上花费额外的半小时加班上瘾。嗨，我是新来的。

这两者之间似乎存在一些参考混淆。

using Plantool.xMap;
using Plantool.xRoute;

你可以删除这些：

using Plantool.xMap;
using Plantool.xLocate;
using Plantool.xRoute;

只需添加以下内容：

using Plantool;

然后显式引用正确的类型，确保您引用的是所需的类型。这应该解决所有三个错误消息。

理想情况下，您应该避免只有命名空间不同的名称冲突。在 .NET 框架中，您会注意到他们小心翼翼地避免这种情况，例如......

System.Data.Odbc.OdbcConnection
 System.Data.SqlClient.SqlConnection

Connection考虑到一个在Odbc命名空间中，一个在命名空间中，它们可能都被称为SqlClient—— 但这可能会导致您遇到的问题。

通过重命名LineString为RouteLineStringandMapLineString您可以避免应用程序中的混淆。

根据我对 xServer 的记忆，这是一个主要问题：xMap、xRoute 和 xLocate 中的常见类型不一样（就像你说的，因为它们是可选模块）。xMap.LineString实际上是与 不同的类型xRoute.LineString，即使它们具有相同的属性。您对此无能为力，除了：

  • 如果两种类型共享一个公共基类型或接口，请改用这个公共类型
  • 编写扩展方法以映射 fromxRoute.LineString到xLocate.LineString...等。

例如：

public static xLocate.LineString ToXLocateLineString(this xRoute.LineString lineString)
{
    return new xLocate.LineString
    {
        // Map type by copying properties
        ....
    };
}

所以你可以写

xRoute.LineString[] input = ....
xMap.LineString[] output = input.Select(z => z.ToXLocateLineString()).ToArray();

甚至

public static xLocate.LineString[] ToXLocateLineStringArray(this xRoute.LineString[] lineString)
{
    return lineString.Select(z => z.ToXLocateLineString()).ToArray();
}

然后

xMap.LineString[] output = input.ToXLocateLineStringArray();

也许他们改进了他们的 API，因为我最后一次使用它，对此不确定。

干杯，在我看来，冗余可以通过正确创建客户端类来解决。您可以使用 Visual Studio 的 WSDL.EXE 在一个步骤中合并 WSDL，而不是一个一个地添加三个 WSDL（通过 Visual Studio 向导）。这适用于 PTV xServer 1（在此线程中引用），甚至更好地适用于 xServer2 我通常做的是 CMD 语句，例如

WSDL /namespace:"XServer" /sharetypes /out:"XServer.cs" "https://xserver2-europe-eu-test.cloud.ptvgroup.com/services/ws/XLocate?wsdl" "https://xserver2 -europe-eu-test.cloud.ptvgroup.com/services/ws/XRoute?wsdl" "https://xserver2-europe-eu-test.cloud.ptvgroup.com/services/ws/XTour?wsdl"

将此视为一般建议。如今的映射接口完全不同。
