如何关闭 EPPlus 中 Excel 应用程序对象的后台错误检查?

How can I turn background error checking off for the Excel app object in EPPlus?

使用笨重、笨重但功能齐全的 Excel Interop,可以像这样关闭后台错误检查:

Excel.Application excelApp = new Excel.Application();
excelApp.ErrorCheckingOptions.BackgroundChecking = false;

...如图所示

我得到的绿色三角形指示错误数字,如下所示:

...我想关闭它。这些只是不应标记为不良或可疑的字符串值。

那么如何使用 EPPlus 关闭 Excel 应用程序对象的后台错误检查,或者以其他方式以编程方式阻止这些绿色三角形?

更新

从这里更改代码:

using (var custNumCell = priceComplianceWorksheet.Cells[rowToPopulate, DETAIL_CUSTNUM_COL])
{
    custNumCell.Style.Font.Size = DATA_FONT_SIZE;
    custNumCell.Value = _custNumber;
    custNumCell.Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
}

...为此:

using (var custNumCell = priceComplianceWorksheet.Cells[rowToPopulate, DETAIL_CUSTNUM_COL])
{
    custNumCell.Style.Font.Size = DATA_FONT_SIZE;
    custNumCell.ConvertValueToAppropriateTypeAndAssign(_custNumber);
    custNumCell.Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
}

// Adapted from 
public static void ConvertValueToAppropriateTypeAndAssign(this ExcelRangeBase range, object value)
{
    string strVal = value.ToString();
    if (!String.IsNullOrEmpty(strVal))
    {
        decimal decVal;
        double dVal;
        int iVal;

        if (decimal.TryParse(strVal, out decVal))
        {
            range.Value = decVal;
        }
        else if (double.TryParse(strVal, out dVal))
        {
            range.Value = dVal;
        }
        else if (Int32.TryParse(strVal, out iVal))
        {
            range.Value = iVal;
        }
        else
        {
            range.Value = strVal;
        }
    }
    else
    {
        range.Value = null;
    }
}

...半固定;现在是:

但请注意,前导“0”被删除了。我需要保留它,所以这仍然只解决了一半。

我尝试了下面评论中指出 的建议,并添加了这段代码:

    //Create the import nodes (note the plural vs singular
    var ignoredErrors = 
priceComplianceWorksheet.CreateNode(XmlNodeType.Element, "ignoredErrors",
xdoc.DocumentElement.NamespaceURI);
    var ignoredError
priceComplianceWorksheet.CreateNode(XmlNodeType.Element, "ignoredError",
xdoc.DocumentElement.NamespaceURI);
    ignoredErrors.AppendChild(ignoredError);

    //Attributes for the INNER node
    var sqrefAtt = priceComplianceWorksheet.CreateAttribute("sqref");
    sqrefAtt.Value = range;

    var flagAtt =
priceComplianceWorksheet.CreateAttribute("numberStoredAsText");
    flagAtt.Value = "1";

    ignoredError.Attributes.Append(sqrefAtt);
    ignoredError.Attributes.Append(flagAtt);

    //Now put the OUTER node into the worksheet xml
   priceComplianceWorksheet.LastChild.AppendChild(ignoredErrors);

...但是 "CreateAttribute" 和 "LastChild" 无法识别...?!?

响应更新 2,您只需要引用 XmlDocument 并使用它来生成 XML:

var xdoc = priceComplianceWorksheet.WorksheetXml;

//Create the import nodes (note the plural vs singular
var ignoredErrors = xdoc.CreateNode(XmlNodeType.Element, "ignoredErrors",xdoc.DocumentElement.NamespaceURI);
var ignoredError = xdoc.CreateNode(XmlNodeType.Element, "ignoredError",xdoc.DocumentElement.NamespaceURI);
ignoredErrors.AppendChild(ignoredError);

//Attributes for the INNER node
var sqrefAtt = xdoc.CreateAttribute("sqref");
sqrefAtt.Value = "C2:C10"; // Or whatever range is needed....

var flagAtt = xdoc.CreateAttribute("numberStoredAsText");
flagAtt.Value = "1";

ignoredError.Attributes.Append(sqrefAtt);
ignoredError.Attributes.Append(flagAtt);

//Now put the OUTER node into the worksheet xml
xdoc.LastChild.AppendChild(ignoredErrors);
