I doubt you will be able to do this unless AutoCAD has an API that you can hook into and ask it to close the file for you. 

Your c# app can only do things to the process (acad.exe) , it doesn't have access to the internal operations of that process.

blocks|key|2082890|text|从Autodesk站点(http://usa.autodesk.com/adsk/servlet/index?id=773204&siteID=123112)获取Autocad+.NET库|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2082891|然后，您将能够使用Application和Document类。它们将使您能够完全控制在应用程序中打开和关闭文档。|style|CODE|2082892|你可以找到许多关于这方面的文章，并可以提出更多的问题。|2082893|entityMap|0|LINK|mutability|MUTABLE|url|http://usa.autodesk.com/adsk/servlet/index?id=773204&siteID=123112^0|C|1U|0|0|9|B|L|8|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]]|C|$]]|$1|D|3|E|5|6|7|V|8|@$A|W|B|X|F|G]|$A|Y|B|Z|F|G]]|9|@]|C|$]]|$1|H|3|I|5|6|7|10|8|@]|9|@]|C|$]]|$1|J|3|-4|5|6|7|11|8|@]|9|@]|C|$]]]|K|$L|$5|M|N|O|C|$P|Q]]]]

Take the Autocad .NET libraries from Autodesk Sites (<a href="http://usa.autodesk.com/adsk/servlet/index?id=773204&amp;siteID=123112">http://usa.autodesk.com/adsk/servlet/index?id=773204&amp;siteID=123112</a>)

Then you will be able to use <code>Application</code> and <code>Document</code> classes.
They will give you full control over opening and closing documents within the application.

You can find many articles on that, and can ask further questions.

blocks|key|4648910|text|此外，您不应该使用Kill，除非进程已经变得没有响应，而且肯定不会在CloseMainWindow之后立即响应。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4648911|CloseMainWindow是要求应用程序自动关闭的一种礼貌方式。Kill就像从插座上拔出电源线一样。你没有给它机会去清理它自己，然后干净利落地退出。|4648912|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Also, you shouldn't use Kill unless the process has become unresponsive and certainly not immediately after CloseMainWindow. 

CloseMainWindow is the polite way to ask an application to close itself. Kill is like pulling the power lead from the socket. You aren't giving it the chance to clean up after itself and exit cleanly.

blocks|key|946254|text|还有另一种可能性-只有当您的C#代码与AutoCAD进程运行在同一台计算机上时，这种方法才能起作用，并不建议这样做，但是，如果您确实遇到了麻烦，并且准备忍受窗口切换的麻烦，您可以使用SendKeys命令向应用程序发送击键。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|946255|MSDN文章点击此处：http://msdn.microsoft.com/EN-US/library/ms171548(v=VS.110,d=hv.2).aspx+http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.send.aspx|offset|length|946256|使用此命令，您可以发送击键来模拟使用菜单命令关闭文件的用户。|946257|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/EN-US/library/ms171548(v=VS.110,d=hv.2).aspx|1|http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.send.aspx^0|0|B|1Y|0|2A|27|1|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|S|8|@]|9|@$D|T|E|U|1|V]|$D|W|E|X|1|Y]]|A|$]]|$1|F|3|G|5|6|7|Z|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|10|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]|P|$5|K|L|M|A|$N|Q]]]]

There is one other possibility - this will only work if your C# code is running on the same machine as the AutoCAD process and it is not really recommended, but, if you are really stuck and are prepared to put up with the hassle of window switching you can send key strokes to an application using the SendKeys command.

MSDN articles here:
<a href="http://msdn.microsoft.com/EN-US/library/ms171548(v=VS.110,d=hv.2).aspx" rel="nofollow">http://msdn.microsoft.com/EN-US/library/ms171548(v=VS.110,d=hv.2).aspx</a>

Using this you could send the key strokes to simulate the user using the menu commands to close the file.

AutoCAD does have an api. there are 4 assemblys. Two for in-process and two for COM.

inprocess :
acdbmgd.dll
acmgd.dll

COMInterop :
Autodesk.Autocad.Interop.dll
Autodesk.Autocad.Interop.Common.dll

this is a method that will open a new instance of AutoCAD or it will connect to an existing running instance of AutoCAD.

you will need to load these .dlls into your project references.

<pre><code>using Autodesk.AutoCAD.Interop;
using Autodesk.AutoCAD.Interop.Common;

namespace YourNameSpace {

public class YourClass {

AcadApplication AcApp;
private const string progID = "AutoCAD.Application.18.2";// this is AutoCAD 2012 program id
private string profileName = "&lt;&lt;Unnamed Profile&gt;&gt;";
private const string acadPath = @"C:\Program Files\Autodesk\AutoCAD 2012 - English\acad.exe";

public void GetAcApp()
 {
 try
 {
 AcApp = (AcadApplication)Marshal.GetActiveObject(progID);

 } catch {
 try {
 var acadProcess = new Process();
 acadProcess.StartInfo.Arguments = string.Format("/nologo /p \"{0}\"", profileName);
 acadProcess.StartInfo.FileName = (@acadPath);
 acadProcess.Start();
 while(AcApp == null)
 {
 try { AcApp = (AcadApplication)Marshal.GetActiveObject(progID); }
 catch { }
 }
 } catch(COMException) {
 MessageBox.Show(String.Format("Cannot create object of type \"{0}\"",progID));
 }
 }
 try {
 int i = 0;
 var appState = AcApp.GetAcadState();
 while (!appState.IsQuiescent)
 {
 if(i == 120)
 {
 Application.Exit();
 }
 // Wait .25s
 Thread.Sleep(250);
 i++;
 }
 if(AcApp != null){
 // set visibility
 AcApp.Visible = true;
 }
 } catch (COMException err) {
 if(err.ErrorCode.ToString() == "-2147417846"){
 Thread.Sleep(5000);
 }
 }
 }
 }
}

closeing it is as simple as

<pre><code>Application.Exit();
</code></pre>

and forgive the code. its atrocious, this was one of my first methods when i just started developing...

I am using visual studio 2010 and I am having a .DWG file which I want to open in autocad. Till now I have used this.

<pre><code>Process p = new Process();
ProcessStartInfo s = new ProcessStartInfo("D:/Test File/" + fileName);
p.StartInfo = s;
p.Start();
</code></pre>

But what I want is to close the file inside the Autocad but not the autocad itself. (Means atocad.exe should be kept running).

Till now I hve used this but its closing the acad.exe not the file. 

<pre><code>foreach (Process Proc in Process.GetProcesses())
{
 if (Proc.ProcessName.Equals("acad"))
 {
 Proc.CloseMainWindow();
 Proc.Kill();
 }
}
</code></pre>

How to close a file in Autocad using C# keeping acad.exe running?
