运行AutoCAD Core控制台
先生们，我找到了一种方法，可以在窗口不可见的情况下运行AutoCAD Core控制台，将secureload设置为0，然后Netload一个dll，运行一个带有参数、GUID字符串的.NET Lisp应用程序。此字符串是进程间通信的管道名称。这允许外部应用程序优雅地处理DWG
与AutoCAD相比，AutoCAD Core控制台本身使用的RAM非常少。当它空闲时，它使用0%的CPU功率。我遇到的问题是，我的应用程序占用了大量CPU资源。我的英特尔I9 CPU有10个内核，20个线程。它100%使用一个线程，占整个CPU的5%。当程序处于空闲状态时，我想将其减少到~0.1%
以下是我在AutoCAD Core控制台中运行的代码
using AcConsole;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.Runtime;
using Clifton.Core.Pipes;
using NetDBX;
using System.Collections.Generic;
using System.IO;
namespace AcConsoleIn
{
///
/// Provides static methods to run within AutoCAD Core Console
///
public static class Run
{
// IPC Pipe
private static ClientPipe Client { get; set; }
///
/// Provides the Lisp Function to connect this process to an external application.
///
///
public static void Process(ResultBuffer buffer)
{
try
{
using (buffer)
{
// Process input
List args = AutoLisp.HandleLispArguments(buffer, 1, 1);
// Create and connect IPC pipe
string pipeName = AutoLisp.LispToString(args);
Client = new ClientPipe(".", pipeName, p => p.StartStringReaderAsync());
Client.DataReceived += Client_DataReceived;
Client.Connect();
}
}
catch { }
}
///
/// Event Handler for processing data from server.
///
///
///
private static void Client_DataReceived(object sender, PipeEventArgs e)
{
// Exit if communication pipe is broken
if (Client == null)
return;
try
{
// Check for a close application message
if (e.String == "Close Application")
{
// Disconnect Pipe
Client.DataReceived -= Client_DataReceived;
Client.Close();
Client = null;
// Close AutoCAD
Autodesk.AutoCAD.ApplicationServices.Core.Application.Quit();
return;
}
// Tell server that this is busy
Client.WriteString("1");
// Get database object
AcConsole.DatabaseServices.Database database;
database = IO.XmlDeserializeFromString(e.String);
// Throw error if it received an invalid database object
if (database == null)
throw new InvalidDataException("Invalid Database Object");
// Create new drawing
using Database drawing = new Database(true, true);
using (Transaction transaction = drawing.TransactionManager.StartTransaction())
{
// Convert AcConsole.DatabaseServices.Database to Autodesk.AutoCAD.DatabaseServices.Database
database.ToDatabase(drawing, transaction);
transaction.Commit();
}
// Delete file if it exists
string filename = database.Filename;
if (File.Exists(filename))
File.Delete(filename);
// Save drawing
drawing.SaveAs(filename, DwgVersion.Current);
// Tell Server it is not busy.
Client.WriteString("0");
}
catch (System.Exception ex)
{
// Tell server that an error occured.
Client.WriteString(ex.Message);
}
}
}
}
我想如果我使用事件处理程序，当它空闲时，我不会使用任何CPU电源。有人能帮我吗？

使用任务呢？

经过更多的检查，它似乎与重定向控制台Standard IO
///
/// Initializes a new instance of this class
///
public Console()
{
try
{
string installpath = null;
// Search the directory for the AutoCAD Console Application
foreach (string file in Directory.GetFiles(@"C:\Program Files\Autodesk\", "accoreconsole.exe", SearchOption.AllDirectories))
{
if (Path.GetFileName(file).Equals("accoreconsole.exe", StringComparison.OrdinalIgnoreCase))
{
installpath = file;
break;
}
}
// Set up process
coreprocess.StartInfo.Arguments = "/isolate";
coreprocess.StartInfo.UseShellExecute = false;
coreprocess.StartInfo.CreateNoWindow = true;
coreprocess.StartInfo.RedirectStandardOutput = false;
coreprocess.StartInfo.RedirectStandardInput = true;
coreprocess.StartInfo.FileName = installpath;
// Start Process
this.ConsoleStarted = coreprocess.Start();
// Load program to AutoCAD Core Console
if (this.ConsoleStarted)
{
// Get program running inside accoreconsole
string loadDLL = Directory.GetCurrentDirectory() + "\\AcConsoleIn.dll";
using StreamWriter writer = coreprocess.StandardInput;
// Set up the IPC pipe connection
string guid = Guid.NewGuid().ToString().ToUpper();
server = new(guid, p => p.StartStringReaderAsync());
server.Connected += Server_Connected;
server.DataReceived += Server_DataReceived;
// Write to AutoCAD Core Console
writer.WriteLine("SECURELOAD 0");
writer.WriteLine("NETLOAD " + loadDLL);
writer.WriteLine("(PROCESS \"" + guid + "\") ");
writer.Close();
}
}
catch { }
}
有关
，如果我注释掉了代码的编写器部分，尽管没有运行任何东西，它仍然以5%的速度运行。但是，如果我更改以下内容：
coreprocess.StartInfo.RedirectStandardInput = false;
它以0%的速度运行。
因此，标准输入的重定向就是这样做的。如何解决此问题？
我需要写入控制台，并且不想运行100%的线程。 改为从文件中读取文本？我假设“ReDirectStandard ardInput”是键盘输入。 我找到了。这是这一行：
writer.Close();
显然，当我删除那一行时，它解决了问题。
你介意分享更多关于这个的信息吗？我会对你的解决方案非常感兴趣
