Gembox.Spreadsheet autofit不能用于前两列C＃

using System; using System.IO; using System.Linq; using System.Xml.Linq; using GemBox.Spreadsheet; namespace ExcelSortingAutomation { public class Program { [STAThread] public static void Main(string[] args) { SpreadsheetInfo.SetLicense("License"); ExcelFile ef = new ExcelFile(); ExcelWorksheet ws = ef.Worksheets.Add("Error Spreadsheet info Elmah"); int i = 0; var checkTime = DateTime.Now; var files = Directory.GetFiles("C:\\ErrorsMay2017", "*.xml"); foreach (string file in files) { var tagElement = XElement.Load(file); var errors = from tagAttribute in tagElement.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() }; int columnCount = ws.CalculateMaxUsedColumns(); 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"); } } } } 

在上面的例子中，我有一个简单的控制台应用程序，用于parsingelmah错误日志，分离出几个关键组件，然后将它们打印到Gembox.spreadsheet中的一系列单元中。 我当前的问题是，使用自动调整设置，我在单元格2-5上获得了正确的样式，但不是0或1.在将自动调整（1）更改为自动调整（0）时，它会正确打印第一个单元格，但删除所有其他人。 有人可以请解释，或提供有关如何打印所有单元格自动格式的见解？

我看到这个代码的几个问题：

• 对于file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。
• ivariables表示errorlogging的索引，换句话说，它表示行索引，所以用它来select一些自动拟合的“随机列”是没有意义的。
• 对于每个error ，表格的头都被重写。
• 在第二次迭代时，表头将覆盖先前写入0索引行的第一个error 。
• 等等。

不过，请尝试以下方法：

 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")))); 

我希望这有帮助。
