Question

这似乎是一个转义字符串的简单问题，但我无法找出正确的格式，我找不到包含Excel页脚中字段示例的文档。

有问题的财产是：

xlSheet.HeaderFooter.OddFooter.LeftAlignedText = "&[Page] of &[Pages]";

以下是为代码生成工作表的更大代码片段：

 using (ExcelPackage pckExport = new ExcelPackage())
            {
                ExcelWorksheet xlSheet = pckExport.Workbook.Worksheets.Add(SystemEnum.GetEnumDescription(typeof(SystemEnum.Reports), SystemEnum.Reports.GroomingCalendarReport.GetHashCode()));
                try
                {
                    int miRow = 1;
                    string pageHeader = "Calendar Report";
                    xlSheet.Cells.Style.Font.Size = 9;
                    xlSheet.Cells.Style.Font.Name = "Times New Roman";
                    DateTime reportDate = Convert.ToDateTime(rptDate);
                    ////set the report header
                    xlSheet.HeaderFooter.OddHeader.CenteredText = "&\"Times New Roman,Bold\"&12" + "\n" + pageHeader + "\n" + " &11for&12 " + reportDate.Date.DayOfWeek.ToString() + " , " + reportDate +
                                                                   "\n" + Location;
                    xlSheet.HeaderFooter.OddFooter.LeftAlignedText = "&[Page] of &[Pages]";
                    xlSheet.HeaderFooter.OddFooter.RightAlignedText = DateTime.Now.ToShortDateString();

生成并打开电子表格并导航到File \ Print菜单后，您会看到页脚不正确：

以下是页脚的屏幕抓取： Page of Pages

如果我进入页面设置并选择自定义页脚，则对话框会将页脚信息正确格式化为＆amp; [Page] of＆amp; [Pages]，如果我单击okay并让对话框关闭打印预览然后显示页脚正确。

以下是自定义页脚对话框的屏幕抓取： Custom Footer Dialog Box

我尝试过使用显式字符串并使用＆amp; [Page]，但它们都会在预览中返回Page] Page]，并且完全是在自定义页脚框中发送的文本。

我已经用尽了寻找帮助的想法。

任何人都可以帮忙吗？

谢谢，

如果您查看ExcelHeaderFooter对象，您会看到一大堆非常有帮助的const，以便您完成所需内容：

var wb = pck.Workbook;
var ws = wb.Worksheets.Add("Sheet1");
ws.Cells[1, 1].Value = "Test";

var footer = $"Page {ExcelHeaderFooter.PageNumber} of {ExcelHeaderFooter.NumberOfPages}";
ws.HeaderFooter.EvenFooter.CenteredText = footer;
ws.HeaderFooter.OddFooter.CenteredText = footer;

以下是4.1版本中列出的内容：

#region Static Properties
/// <summary>
/// The code for "current page #"
/// </summary>
public const string PageNumber = @"&P";
/// <summary>
/// The code for "total pages"
/// </summary>
public const string NumberOfPages = @"&N";
/// <summary>
/// The code for "text font color"
/// RGB Color is specified as RRGGBB
/// Theme Color is specified as TTSNN where TT is the theme color Id, S is either "+" or "-" of the tint/shade value, NN is the tint/shade value.
/// </summary>
public const string FontColor = @"&K";
