Question

我们正在构建一个新的WebApi。我们开始在暑假前使用.Net Core Rc1 - 现在，.Net Core为1.0我想更新。

但是我遇到了一些问题 - 如果我能解决的话，我无法弄明白？

挑战在于我需要引用一些.Net 4.5.1 x86程序集。

这意味着我需要使用允许使用.Net 4.5.1的名字 - 如果我需要这两个世界，据我所知 - 只有netstandard16可用。（https://docs.microsoft.com/da-dk/dotnet/articles/standard/library）

但后来我遇到了.Net 4.6.3（或上面链接中的vNext）尚未出现的问题。

如果我参考netstandard15 - 那么AspNetCore库就无法工作。

如果我引用netstandard16 - 那么我会收到以下错误

error : Can not find runtime target for framework '.NETStandard,Version=v1.6' compatible with one of the target runtimes: 'win10-x64, win81-x64, win8-x64, win7-x64'. Possible causes:
error : 1. The project has not been restored or restore failed - run `dotnet restore`
error : 2. The project does not list one of 'win10-x64, win81-x64, win8-x64, win7-x64' in the 'runtimes' section.
error : 3. You may be trying to publish a library, which is not supported. Use `dotnet pack` to distribute libraries.

是否可以使用当前可用位来执行以下操作

在.Net 4.5中为x86编译了一个业务层（需要重用它 - 遗产很棒）
创建Asp.Net核心网站
在网站中引用业务层 - 只进行编码

有人能帮助我吗？

Answer 1

如果您需要.NET Core应用程序，则应使用using Excel = Microsoft.Office.Interop.Excel; using VBE = Microsoft.Vbe.Interop.Forms; private static void ExcelOperation(string xlFileName) { var xlApp = new Excel.Application(); var xlWorkbook = xlApp.Workbooks.Open(xlFileName); var xlSheet = xlWorkbook.Worksheets["your_sheet_Name"] as Excel.Worksheet; try { Excel.OLEObjects oleObjects = xlSheet.OLEObjects() as Excel.OLEObjects; foreach (Excel.OLEObject item in oleObjects) { if (item.progID == "Forms.TextBox.1") { VBE.TextBox xlTB = item.Object as VBE.TextBox; Console.WriteLine("Name: " + item.Name); Console.WriteLine("Text: " + xlTB.Text); Console.WriteLine("Value: " + xlTB.get_Value()); Marshal.ReleaseComObject(xlTB); xlTB = null; } else if (item.progID == "Forms.CheckBox.1") { VBE.CheckBox xlCB = item.Object as VBE.CheckBox; Console.WriteLine("checkbox: " + item.Name); Console.WriteLine("Value: " + xlCB.get_Value()); Marshal.ReleaseComObject(xlCB); xlCB = null; } } Marshal.ReleaseComObject(oleObjects); oleObjects = null; } catch(Exception ex) { Console.WriteLine(ex.Message); } Marshal.ReleaseComObject(xlSheet); xlSheet = null; xlWorkbook.Close(); Marshal.ReleaseComObject(xlWorkbook); xlWorkbook = null; Marshal.ReleaseComObject(xlApp); xlApp = null; }目标框架。您可能无法在.NET Core应用程序中引用.NET 4.5.1库。

您还可以像这样定位桌面（完整）.NET Framework：

netcoreapp1.0

现在您可以使用.NET 4.5.1库，但您的应用程序不再在.NET Core运行时上运行。

您也可以定位更高版本的.NET，例如`net461。
