在CodeCompiler的构造函数中，调用了下面的方法。在编译之前，先删除CompiledAssemblies文件夹下已经编译好的文件。

// Triton.Common.CodeCompiler
// Token: 0x0600155E RID: 5470 RVA: 0x000CE98C File Offset: 0x000CCB8C
private static void smethod_1()
{
    string path = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), "CompiledAssemblies");
    if (!Directory.Exists(path))
    {
        Directory.CreateDirectory(path);
    }
    foreach (string path2 in Directory.GetFiles(path, "*.*", SearchOption.AllDirectories))
    {
        try
        {
            File.Delete(path2);
        }
        catch (Exception)
        {
        }
    }
    foreach (string path3 in Directory.GetDirectories(path))
    {
        try
        {
            Directory.Delete(path3);
        }
        catch (Exception)
        {
        }
    }
    if (!Directory.Exists(CodeCompiler.CompiledAssemblyPath))
    {
        Directory.CreateDirectory(CodeCompiler.CompiledAssemblyPath);
    }
}

问题

如下代码无法通过编译

using System;
using System.Linq;
using System.Xml.Linq;

namespace HREngine.Bots
{
    public class XmlHelper
    {
        private static XElement _cardDatabase;

        public static string GetCardNameByCardId(string filePath, string cardId)
        {
            if (_cardDatabase == null)
            {
                _cardDatabase = XElement.Load(filePath);
            }

            var tempTargetElement = _cardDatabase.Elements("Entity")
                .FirstOrDefault(x => x.Attribute("CardID")?.Value == cardId);
            var tempTargetElement2 = tempTargetElement?.Elements("Tag")
                .FirstOrDefault(x => x.Attribute("name")?.Value == "CARDNAME");
            XElement targetElement = tempTargetElement2?.Element("enUS");
            if (targetElement == null)
            {
                throw new Exception(string.Format("Can not find card by Id {0}", cardId));
            }

            return targetElement.Value;
        }
    }
}

修复

之前的CSharpCodeProvider 是https://docs.microsoft.com/en-us/dotnet/api/microsoft.csharp.csharpcodeprovider?view=dotnet-plat-ext-3.1

把这个类替换成https://www.nuget.org/packages/Microsoft.CodeDom.Providers.DotNetCompilerPlatform/ 里面的同名的类

Reload的逻辑

                    }
                }
                else
                {
                    this.Instances.AddRange(new TypeLoader<T>(codeCompiler.CompiledAssembly, null));

    }
    using (List<T>.Enumerator enumerator2 = new TypeLoader<T>(null, null).GetEnumerator())

    }
    if (this.eventHandler_0 != null)

string_0的赋值

// Token: 0x06001551 RID: 5457 RVA: 0x000CE580 File Offset: 0x000CC780
        public AssemblyLoader(string directory, bool detectFileChanges)
