基于 Extended WPF Toolkit 我想为CommonNumericUpDown<Station>沿路线的 AutoCAD 站创建自己的。这在 StandAlone-WPF-App 中工作得很好。如果我从磁盘上的任何位置在 AutoCAD 中对其进行网络加载，我会收到 XamlParseException“方法或操作未实现。”，但是将我的 dll 放在 AutoCAD-install-directory 中也可以正常工作。CommonNumericUpDown<Double>还可以很好地创作我自己的作品。该错误也只会在设置 UpDownBase 的属性之一时出现。AutoCAD 在哪里欺骗我？

这是我的代码。为了尽可能简化，我扩展了UpDownBase<T>.

using System;
using System.Windows;

using Xceed.Wpf.Toolkit.Primitives;

using Autodesk.AutoCAD.Runtime;

namespace My.AutoCAD.UITest
{
    class UpDownBaseDoubleUpDown : UpDownBase<double>
    {
        protected override double ConvertTextToValue(string text)
        {
            return double.Parse(text);
        }

        protected override string ConvertValueToText()
        {
            return Value.ToString();
        }

        protected override void OnDecrement()
        {
            Value -= 1;
        }

        protected override void OnIncrement()
        {
            Value += 1;
        }

        protected override void SetValidSpinDirection() { }

        static UpDownBaseDoubleUpDown()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(UpDownBaseDoubleUpDown), new FrameworkPropertyMetadata(typeof(UpDownBaseDoubleUpDown)));
        }
    }

    public struct Station : IFormattable, IComparable<Station>
    {
        public double Value { get; set; }

        public Station(double value) { Value = value; }

        public int CompareTo(Station other)
        {
            return Value.CompareTo(other.Value);
        }

        public static Station Parse(string s) { return new Station(double.Parse(s)); }

        public override string ToString() { return Value.ToString(); }
        public string ToString(string format, IFormatProvider formatProvider)
        {
            return Value.ToString(format, formatProvider);
        }
    }

    public class UpDownBaseStationUpDown : UpDownBase<Station>
    {
        protected override Station ConvertTextToValue(string text)
        {
            return Station.Parse(text);
        }

        protected override string ConvertValueToText()
        {
            return Value.ToString();
        }

        protected override void OnDecrement()
        {
            Value = new Station(Value.Value - 1);
        }

        protected override void OnIncrement()
        {
            Value = new Station(Value.Value + 1);
        }

        protected override void SetValidSpinDirection() { }

        static UpDownBaseStationUpDown()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(UpDownBaseStationUpDown), new FrameworkPropertyMetadata(typeof(UpDownBaseStationUpDown)));
        }
    }

    /// <summary>Interaction logic for StationUpDownTest.xaml</summary>
    public partial class StationUpDownTest : Window
    {
        public StationUpDownTest()
        {
            InitializeComponent();
        }
    }

    public class Commands
    {
        [CommandMethod("TestMgdStationUpDown")]
        public void TestMgdStationUpDown()
        {
            var dlg = new StationUpDownTest();
            Autodesk.AutoCAD.ApplicationServices.Core.Application.ShowModalWindow(dlg);
        }
    }
}

下载并安装Process Explorer，选择 acad.exe 进程，然后在上下文菜单、Properties...、. NET Assemblies选项卡中检查加载了哪些程序集。可能是另一个扩展加载了旧版本的扩展 WPF 工具包。

也可以使用Fuslogvw来检查是否没有绑定问题。

经过几天的尝试，我发现即使删除了扩展 WPF 工具包，错误仍然存​​在。我还发现了以下问题：WPF 4.0 Application load error in some environment

我的同事通过附加AppDomain.CurrentDomain.AssemblyResolve += ResolveAssembly;和返回解决了这个问题Assembly.LoadFile (assemblyPath);
