我在使用DocumentFormat.OpenXML验证Excel文件时收到此错误（＆＃34;异常抛出：＆＃39; Xunit.Sdk.EqualException＆＃39;在xunit.assert.dll＆＃34;中）。我想使用＃验证excel文件，我正在使用DocumentFormat.OpenXML

            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();

                    OpenXmlValidator v = new OpenXmlValidator(DocumentFormat.OpenXml.FileFormatVersions.Office2013);
                    var errs = v.Validate(doc);
                    Assert.Equal(1, errs.Count());
                }
            }
        }
    }

Answer 1

可以检查此方法以进行验证：

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);
    }
}

Answer 2

如果未在SpreadsheetDocument或损坏的文档中读取excel文件

DocumentFormat.OpenXml.Packaging.OpenXmlPackageException：“指定的包无效。缺少主要部分。“

如果Assert.Equal（1，errs.Count（））;

System.InvalidOperationException：“Assert.Equals不应该用于Assertions，而是使用Assert.AreEqual（...）。”

你可以尝试

Assert.Equal（0，errs.Count（））;

我用

<package id="DocumentFormat.OpenXml" version="2.8.1" targetFramework="net45" /> <package id="NUnit" version="3.10.1" targetFramework="net45" />

使用Documentformat.OpenXML在c＃中验证Excel文件
