C# 如何将Excel VSTO的程序集位置分配给安装？
我正在创建一个用C#编写的文档级工作簿/模板，并使用VSTO安装程序部署代码。安装项目后，我拥有电子表格的全部功能，但是，当我将已安装的工作表保存或复制到安装文件夹外的另一个路径时，我收到以下错误： 详情如下:C# 如何将Excel VSTO的程序集位置分配给安装？,c#,installation,vsto,C#,Installation,Vsto,我正在创建一个用C#编写的文档级工作簿/模板，并使用VSTO安装程序部署代码。安装项目后，我拥有电子表格的全部功能，但是，当我将已安装的工作表保存或复制到安装文件夹外的另一个路径时，我收到以下错误： 详情如下: Name: From: file:///C:/Users/Kronos/Desktop/ExcelTemplate1.vsto ************** Exception Text ************** System.Deployment.Application.De

没用。您需要按照您参考的中概述的说明进行操作，只需稍微多做一点。然而，这有点混乱，文章中有一个错误。希望这将有助于澄清： 您需要定义一个与本文提供的类似的用户脚本 在本文中有一个包含项目示例的文件。从那里，您可以针对该cs项目的输出引用您的
自定义操作。创建一个新的CS类库项目，复制以下特定于解决问题的用户脚本：

public override void Install(IDictionary stateSaver)

string[] nonpublicCachedDataMembers = null;
// Use the following for debugging during the install

if (Uri.TryCreate(

out deploymentManifestLocation) == false)
{
throw new InstallException(

}
string documentLocation =

}

}
// use the following for debugging
MessageBox.Show(documentLocation);
if (ServerDocument.IsCustomized(documentLocation))
{
ServerDocument.RemoveCustomization(documentLocation);
}
ServerDocument.AddCustomization(
documentLocation,
assemblyLocation,
SolutionID,
deploymentManifestLocation,
false,
out nonpublicCachedDataMembers);
stateSaver.Add("documentlocation", documentLocation);
base.Install(stateSaver);
}
public override void Commit(IDictionary savedState)
{
base.Commit(savedState);
}
public override void Rollback(IDictionary savedState)
{
base.Rollback(savedState);
}
public override void Uninstall(IDictionary savedState)
{
base.Uninstall(savedState);

}
}
这将覆盖安装程序的安装过程。base.Install（stateSaver）
调用代码的其余部分继续正常安装
MSDN文章中的错误：
文章说，在安装自定义操作的CustomActionData
中使用以下内容：
/assemblyLocation="[TARGETDIR]<YourProjectName>.dll"/deploymentManifestLocation="[TARGETDIR]<YourProjectName>.vsto"/documentLocation="[TARGETDIR]<YourProjectName>.xltx"
/assemblyLocation=“[TARGETDIR].dll”/deploymentManifestLocation=“[TARGETDIR].vsto”/documentLocation=“[TARGETDIR].xltx”
但是，应该是这样的（注意参数之间的空格）：
/assemblyLocation=“[TARGETDIR].dll”/deploymentManifestLocation=“[TARGETDIR].vsto”/documentLocation=“[TARGETDIR].xltx”
这应该可以解决您的问题，但是在重新构建安装程序之前，请确保将对Excel项目的任何更改重新构建到发布版本，因为它指向的是发布版本，而不是调试版本。虽然James Mertz的答案很正确，但它也有点过时（尽管它只是在我拔了一天头发后救了我一命）。对于较新版本的Visual Studio，此部分应用程序构建的说明已移至。我建议你去读，或者你可以读我的《悬崖笔记》版本如下：
应在现有解决方案中作为新项目构建的新控制台应用程序。Program.cs
应该如下所示：

}
break;

break;

}
}
必须更改dll、vsto、工作簿和解决方案id的设置。解决方案ID可以在.csproj
文件中找到（在文件资源管理器中找到并在记事本中打开）
现在你是金色的。应用程序成功安装后，将启动此控制台应用程序，并将工作簿的manifestLocation
更改为安装路径，而不是当前工作簿的相对路径
如果安装人员在其计算机上没有管理员权限，而您正在将其安装到Program Files目录中，您可能会发现，在执行此步骤之前，他们可以安装并运行，但在执行此步骤之后，他们无法安装并运行。这是因为工作簿在该位置是只读的。在这种情况下，您必须选择另一个位置安装应用程序（AppDataLocal是一个不错的选择）。感谢您在此处分享信息，特别是MSDN文章中有关错误的信息。我正准备把我的脚穿过这个屏幕。（微软不会校对和检查他们的资料的准确性？？？）@StevenC.Britton欢迎您，但是我建议您使用install shield安装。它的使用和设置更容易一些。
