c# - 使用 Documentformat.OpenXML 在 c# 中验证 Excel 文件

Question

我在使用 DocumentFormat.OpenXML 验证 Excel 文件时收到此错误（“异常抛出：xunit.assert.dll 中的'Xunit.Sdk.EqualException'”）。我想使用 # 验证 excel 文件，我正在使用 DocumentFormat.OpenXML

using System.IO.Packaging;
using System.Linq;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Validation;
using Xunit;
using P = DocumentFormat.OpenXml.Presentation;
using S = DocumentFormat.OpenXml.Spreadsheet;
using W = DocumentFormat.OpenXml.Wordprocessing;
using A = DocumentFormat.OpenXml.Drawing;

namespace ExcelValidation2

    class Program
    {
        static void Main(string[] args)
        {
            var excelFile = "ExcelValidation.xlsx";
            var readFile = File.ReadAllBytes(excelFile);
            using(MemoryStream ms = new MemoryStream())
            {
                ms.Write(readFile, 0, readFile.Length);
                using (SpreadsheetDocument doc = SpreadsheetDocument.Open(ms, true))
                {
                    //var corePart = doc.CoreFilePropertiesPart;
                    //var appPart = doc.ExtendedFilePropertiesPart;
                    //doc.DeletePart(corePart);
                    //doc.DeletePart(appPart);
                    //doc.AddCoreFilePropertiesPart();
                    //doc.AddExtendedFilePropertiesPart();
                    //doc.AddCustomFilePropertiesPart();
                    //doc.AddDigitalSignatureOriginPart();

                    //doc.DeletePart(tnPart);
                    //tnPart = doc.AddThumbnailPart("image/jpg");
                    OpenXmlValidator v = new OpenXmlValidator(DocumentFormat.OpenXml.FileFormatVersions.Office2013);
                    var errs = v.Validate(doc);
                    Assert.Equal(1, errs.Count());
                }
            }
        }
    }
}

可以检查这个方法来验证：

private void ValidateExcel()
{
    try
    {
        var validator = new OpenXmlValidator();
        int count = 0;
        foreach (ValidationErrorInfo error in validator.Validate(SpreadsheetDocument.Open(openFileDialog1.FileName, true)))
        {

            count++;
            lblError.Text += ("Error Count : " + count) + "\r\n";
            lblError.Text += ("Description : " + error.Description) + "\r\n";
            lblError.Text += ("Path: " + error.Path.XPath) + "\r\n";
            lblError.Text += ("Part: " + error.Part.Uri) + "\r\n";
        }
        Console.ReadKey();
    }
    catch (Exception ex)
    {
        lblError.Text += (ex.Message);
    }
}
