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;
        }
    }
}

 

"The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?)"

The type or namespace name 'Xml' does not exist in the namespace 'System' (are you missing an assembly reference?)

The type or namespace name 'XElement' could not be found (are you missing a using directive or an assembly reference?)

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

            if (compilerResults != null)
            {

                {

                    {
                        this.ilog_0.Error("Compiler Error: " + obj.ToString());
                    }
                }
                else
                {
                    this.Instances.AddRange(new TypeLoader<T>(codeCompiler.CompiledAssembly, null));
                }
            }
        }
        catch (Exception ex)
        {

            else
            {
                this.ilog_0.Error("[Reload] An exception occurred.", ex);
            }
        }
    }
    using (List<T>.Enumerator enumerator2 = new TypeLoader<T>(null, null).GetEnumerator())
    {
        while (enumerator2.MoveNext())
        {

    }
    if (this.eventHandler_0 != null)
    {
        this.eventHandler_0(this, null);

}

 

string_0的赋值

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