如何从其他C#项目中调用VSTO类 [英] How to call VSTO class from other c# project
问题描述
在我的解决方案中，我有2个项目.
In my solution I have 2 projects.
一个是控制器，在最终产品中，该控制器用于检查是否从控制台/非用户输入发出执行，因此将基于xml文件的输入在后台执行想要的更改，或者执行是由用户输入发出的，它将打开一个界面.
One is the controller, which in the final product is used to check if a execution is issued from console/non user input and therefore will execute the wanted changes in background based on imput from a xml-file, or if the execution was issued by user input, which will open an interface.
非用户输入可能是计划中的任务或类似的任务，但是那是另一回事了，我只是为某些情况而写.
A non user input would maybe a planed task or something like that, but thats is for an other time now and I just write that for some context.
在这两种情况下，迟早都需要访问Word文档以及读取，写入和更改文档属性.
In both cases, sooner or later there is the need to access word-documents and read, write and change document-properties.
为此，我创建了一个具有所需功能的VSTO-Word-Addin，到目前为止，我对路径进行了硬编码，并且除其他文档外没有返回结果.
To do that I created a VSTO-Word-Addin with the needed functions and up to this point I hardcoded the paths and didn't return the results anywhere else than an other document.
由于我确信我在VSTO中的代码可以正常工作，因此我想将原型扩展到下一个级别，并尝试在控制台和VSTO之间添加连接.
Since I am sure my code in VSTO itself works, I wanted to extend the prototype to the next level and tried adding the connections between console and VSTO.
为了进行测试，我稍微简化了过程，只是尝试在没有任何用户输入的情况下在控制台和VSTO之间建立连接，并尝试执行一些方法来测试我的VSTO的功能.
For testing I am simplifying the process a bit and just try to establish the connection between console and VSTO without any userinput and trying to execute some methods to test functionality of my VSTO.
我的方法是打开控制台，然后打开Word/插件，打开隐藏的文件并进行魔术操作.
My approach was to open the console, which then opens Word/the addin, open the file hidden and do the magic.
首先要做的是设置要打开的文档的路径，然后用返回的值调用多个方法.
First thing to do is to set a path for the document to be opened and then call multiple methods with returned values.
在这种情况下，我的VSTO返回true
In this case my VSTO returns a true for
SetCustomProperty
和一个新的元组列表
GetCustomProperties
这些是占位符，将在开发中被替换.
Those are placeholders and will be replaced in developement.
我已经尝试了一些可能的解决方案，但是大多数方法都是从VSTO中启动WinForms/WPF/Console，或者尝试从其AddIn调用另一个AddIn.
I already tried some possible solutions, but most of them go the other way around to start a WinForms/WPF/Console out of VSTO or try to call an other AddIn from their AddIn.
我最成功的方法是:
MSDN 通过其他Office解决方案在VSTO加载项中调用代码
MSDN Calling Code in VSTO Add-ins from Other Office Solutions
但是这当然是办公室用的，所以我遇到了无法使用的问题
But of course this is for office so I hit the problem of not being able to use
Globals
有关Globals的更多信息，请参见在MSDN中
More info about Globals can be found here in MSDN
所以也许我错过了要点，只是盲目，但是如何从控制台调用VSTO项目中的类?
So maybe I am missing the point and am just blind, but how can I call a class in a VSTO-project from console?
以下是我当前失败的一些代码示例:
Here are some codesamples of my current failure:
具有我要访问的使用的接口的类:
The class with the used interface I want to access:
[ComVisible(true)]
public interface IPropertyReadWriter
{
bool Open(string Path);
bool SetCustomProperty(String Name, PropertyTypes Type, object Value);
List<Tuple<String, PropertyTypes, object>> GetCustomProperties();
}
[ComVisible(true)]
public class PropertyReaderWriter : IPropertyReadWriter
{
public List<Tuple<string, PropertyTypes, object>> GetCustomProperties()
{
return new List<Tuple<string, PropertyTypes, object>>();
}
public bool Open(string Path)
{
return false;
}
public bool SetCustomProperty(string Name, PropertyTypes Type, object Value)
{
return false;
}
}
MSDN文章中有关从其他Office项目进行调用的代码:
The code used in the MSDN article about calling from other office-project:
object addInName = "ExcelImportData";
Office.COMAddIn addIn = Globals.ThisAddIn.Application.COMAddIns.Item(ref addInName);
ExcelImportData.IAddInUtilities utilities = (ExcelImportData.IAddInUtilities)addIn.Object;
utilities.ImportData();
我不知道如何利用它，因为我无法访问VSTO的Globals异地?
I dont know how to make use of this, because I don't have access to Globals outsite of VSTO?
类似的问题，由于缺少上下文或示例，我无法使用，但无法回答:
Somewhat similar question on so with no answer I could use, because lack of context or example:
我不知道DanByström的答案是什么意思，也不是Mike Regan的答案导致先前提到的MSDN.
I don't know what Dan Byström meant with his answer, also Mike Regan's answer lead to prior stated MSDN.
推荐答案
首先，在您要调用的Addin中添加一个接口:
First, to your Addin that you want to call into add an Interface:
[ComVisible(true)]
public interface IExcelUtilities
{
bool DoSomething();
}
接下来，添加一个实现该接口的类:
Next, add a class that implements the interface:
[ComVisible(true)]
[ClassInterface(ClassInterfaceType.None)]
public class AddInUtilities :
StandardOleMarshalObject,
IExcelUtilities
{
public bool DoSomething()
{
return true;
}
}
然后在ThisAddin.cs中覆盖对象RequestComAddInAutomationService:
Then override object RequestComAddInAutomationService in ThisAddin.cs:
private AddInUtilities utilities;
protected override object RequestComAddInAutomationService()
{
try
{
if (utilities == null)
{
utilities = new AddInUtilities();
}
return utilities;
}
catch (System.Exception ex)
{
// Catch your ex here
}
}
现在，您应该能够像这样从外部应用程序调用公开的方法:
Now you should be able to call the exposed method from your external application like this:
foreach (COMAddIn comaddin in addins)
{
if (comaddin.ProgId.Equals("YourAddinNameHere", StringComparison.InvariantCultureIgnoreCase) == true)
{
bool returnvalue = comaddin.Object.DoSomething();
break;
}
}
