            int i = 0;
            var checkTime = DateTime.Now;

            var files = Directory.GetFiles("C:\ErrorsMay2017", "*.xml");

                                 .Select(x => x.Descendants("value").First().Attribute("string").Value).SingleOrDefault()

                             };

                foreach (var error in errors)
                {
                    // generates table head 
                    ws.Cells[0, 0].Value = "errorID";
                    ws.Cells[0, 1].Value = "type";
                    ws.Cells[0, 2].Value = "message";
                    ws.Cells[0, 3].Value = "time";
                    ws.Cells[0, 4].Value = "Http_Host";
                    ws.Cells[0, 5].Value = "Path_Info";


                    if (i < columnCount)
                    {
                        ws.Columns[i].AutoFit(1, ws.Rows[1], ws.Rows[ws.Rows.Count - 1]);
                    }

                    Console.Write(error);

                    ws.Cells[i, 0].Value = error.errorID;
                    ws.Cells[i, 1].Value = error.type;
                    ws.Cells[i, 2].Value = error.message;
                    ws.Cells[i, 3].Value = error.time;
                    ws.Cells[i, 4].Value = error.PathInfo;
                    ws.Cells[i, 5].Value = error.HttpHost;

                    i++;
                }
                ef.Save("C:\ErrorsMay2017\errorlog " + checkTime.ToString("MM-dd-yyyy-HH-mm") + ".xls");


            }
        }
    }
}

在上面的示例中，我有一个简单的控制台应用程序，它解析 elmah 错误日志，分离出几个关键组件，然后将它们打印到 Gembox.spreadsheet 中的一系列单元格中。我当前的问题是，使用 Autofit 设置，我在单元格 2-5 上获得了正确的样式，但在 0 或 1 上却没有。将 Autofit(1) 更改为 AutoFit(0) 时，它正确地打印了第一个单元格，但是删除所有其他人。有人可以解释一下，或者让我了解如何使用自动格式打印所有单元格吗？

Answer 1

我发现该代码有几个问题：

对于 files 中的每个 file，都会保存一个新的 XLS 文件，这很容易导致重写以前的 XLS 文件。
i变量代表error记录的索引，换句话说它代表行索引，所以用它来select一些[=35=没有意义] 这是自动安装的。
每 error 重写 table 的头部。
在第二次迭代中，table 的头部将覆盖先前写在 0 索引行上的第一个 error。
等等

尽管如此，请尝试以下操作：

SpreadsheetInfo.SetLicense("License");
ExcelFile ef = new ExcelFile();
ExcelWorksheet ws = ef.Worksheets.Add("Error Spreadsheet info Elmah");

// Write header row.
ws.Cells[0, 0].Value = "Error ID";
ws.Cells[0, 1].Value = "Type";
ws.Cells[0, 2].Value = "Message";
ws.Cells[0, 3].Value = "Time";
ws.Cells[0, 4].Value = "Path Info";
ws.Cells[0, 5].Value = "HTTP Host";

int rowIndex = 1;
string folder = @"C:\ErrorsMay2017";

// I presume you want to write data from all XML files into a single spreadsheet.
foreach (string file in Directory.GetFiles(folder, "*.xml"))
{
    // Get errors records.
    var errors = from tagAttribute in XElement.Load(file).DescendantsAndSelf("error").OrderBy(x => x.Attribute("type"))
                 select new
                 {
                     ErrorID = (string)tagAttribute.Attribute("errorId"),
                     Type = (string)tagAttribute.Attribute("type"),
                     Message = (string)tagAttribute.Attribute("message"),
                     Time = (string)tagAttribute.Attribute("time"),

                     PathInfo = tagAttribute.Elements("serverVariables").Descendants("item").Where(x => x.Attribute("name").Value == "PATH_INFO")
                     .Select(x => x.Descendants("value").First().Attribute("string").Value).SingleOrDefault(),

                     HttpHost = tagAttribute.Elements("serverVariables").Descendants("item").Where(x => x.Attribute("name").Value == "HTTP_HOST")
                     .Select(x => x.Descendants("value").First().Attribute("string").Value).SingleOrDefault()
                 };

    // Write errors rows.
    foreach (var error in errors)
    {
        ws.Cells[rowIndex, 0].Value = error.ErrorID;
        ws.Cells[rowIndex, 1].Value = error.Type;
        ws.Cells[rowIndex, 2].Value = error.Message;
        ws.Cells[rowIndex, 3].Value = error.Time;
        ws.Cells[rowIndex, 4].Value = error.PathInfo;
        ws.Cells[rowIndex, 5].Value = error.HttpHost;
        ++rowIndex;
    }
}

// AutoFit columns after writing all spreadsheet's data.
int columnCount = ws.CalculateMaxUsedColumns();
for (int columnIndex = 0; columnIndex < columnCount; ++columnIndex)
    ws.Columns[columnIndex].AutoFit();

// Save to newer Excel format (.xlsx).
ef.Save(Path.Combine(folder,
    string.Format("errorlog {0}.xlsx", DateTime.Now.ToString("MM-dd-yyyy-HH-mm"))));

希望对您有所帮助。
