小编Tac*_*han的帖子

这就是我在做的事情:

CellFormat cellFormat = 
                new CellFormat() 
                { NumberFormatId = (UInt32Value)14U, 
                    FontId = (UInt32Value)0U, 
                    FillId = (UInt32Value)0U, 
                    BorderId = (UInt32Value)0U, 
                    FormatId = (UInt32Value)0U, 
                    ApplyNumberFormat = true };

sd.WorkbookPart.WorkbookStylesPart.Stylesheet.CellFormats.AppendChild<CellFormat>(cellFormat);

_dateStyleIndex = sd.WorkbookPart.WorkbookStylesPart.Stylesheet.CellFormats.Count() - 1;

然后在我的代码后面的某个地方

else if (type == DataTypes.DateTime)
{                
    DateTime dateTime = DateTime.Parse(text);
    double oaValue = dateTime.ToOADate();
    cell.CellValue = new CellValue(oaValue.ToString(CultureInfo.InvariantCulture));
    cell.DataType = new EnumValue<CellValues>(CellValues.Date);
    cell.StyleIndex = Convert.ToUInt32(_dateStyleIndex);               
}

但是,当我使用Open XML SDK Tool验证生成的excel文件时,我收到以下验证错误:属性't'具有无效值'd'.枚举约束失败.

我在这里错过了什么？提前谢谢你的帮助.

PS:添加,这就是x:sheetData的样子.它给了我验证错误:

<x:sheetData xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
  <x:row r="2">
    <x:c r="B2" t="s">
      <x:v>0</x:v>
    </x:c>
    <x:c r="C2" t="s">
      <x:v>1</x:v>
    </x:c> …

我正在尝试在我的 .xlsx 文件中格式化十进制和整数，如“1,000.00”。

生成样式表的代码：

private Stylesheet GenerateStylesheet()
{
    //styling and formatting
    var cellFormats = new CellFormats();
    uint iExcelIndex = 164;

    //number formats
    var numericFormats = new NumberingFormats();
    var nformat4Decimal = new NumberingFormat
    {
        NumberFormatId = UInt32Value.FromUInt32(iExcelIndex++),
        FormatCode = StringValue.FromString("#,##0.00")
    };
    numericFormats.Append(nformat4Decimal);    

    //cell formats
    var cellFormat = new CellFormat
    {
        NumberFormatId = nformat4Decimal.NumberFormatId,
        FontId = 0,
        FillId = 0,
        BorderId = 0,
        FormatId = 0,
        ApplyNumberFormat = BooleanValue.FromBoolean(true)
    };
    cellFormats.Append(cellFormat);

    numericFormats.Count = UInt32Value.FromUInt32((uint)numericFormats.ChildElements.Count);
    cellFormats.Count = UInt32Value.FromUInt32((uint)cellFormats.ChildElements.Count);

    var stylesheet = new Stylesheet(); …

我正在尝试使用openxml从工作表中删除所有公式。这是我正在尝试的：

internal static void ReplaceFormulaWithValue()
{
    var res = _worksheetPart.Worksheet.GetFirstChild<SheetData>().Elements<Row>();      

    foreach (Row row in _worksheetPart.Worksheet.GetFirstChild<SheetData>().Elements<Row>())
    {
        foreach (Cell cell in row.Elements<Cell>())
        {
            if (cell.CellFormula != null &&
                  cell.CellValue != null)
            {
                string cellRef = cell.CellReference;
                CalculationChainPart calculationChainPart = _spreadSheet.WorkbookPart.CalculationChainPart;
                CalculationChain calculationChain = calculationChainPart.CalculationChain;
                var calculationCells = calculationChain.Elements<CalculationCell>().ToList();
                CalculationCell calculationCell = calculationCells.Where(c => c.CellReference == cellRef).FirstOrDefault();
                //CalculationCell calculationCell = calculationChain.Elements<CalculationCell>().Where(c => c.CellReference == cell.CellReference).FirstOrDefault();

                string value = cell.CellValue.InnerText;
                UpdateCell(cell, DataTypes.String, value);

                cell.CellFormula.Remove();
                calculationCell.Remove();                   
            }
        }
    }
    SaveChanges();
}

打开excel文档时，出现以下错误：

我有一个查询,我遍历一个表 - >为每个条目我迭代通过另一个表,然后计算一些结果.我使用游标迭代表.此查询需要很长时间才能完成.总是超过3分钟.如果我在C#中做类似的事情,其中​​表是数组或字典,它甚至不需要一秒钟.我做错了什么,如何提高效率？

DELETE FROM [QueryScores]
GO

INSERT INTO [QueryScores] (Id)
SELECT Id FROM [Documents]

DECLARE @Id NVARCHAR(50)

DECLARE myCursor CURSOR LOCAL FAST_FORWARD FOR
SELECT [Id] FROM [QueryScores]

OPEN myCursor

FETCH NEXT FROM myCursor INTO @Id

WHILE @@FETCH_STATUS = 0
    BEGIN
        DECLARE @Score FLOAT = 0.0

        DECLARE @CounterMax INT = (SELECT COUNT(*) FROM [Query])
        DECLARE @Counter INT = 0

        PRINT 'Document: ' + CAST(@Id AS VARCHAR)
        PRINT 'Score: ' + CAST(@Score AS VARCHAR)

        WHILE @Counter < @CounterMax
            BEGIN

我有一个返回 Guid 列表的方法。我想要以下 linq 查询：

var results = (from t in CurrentDataSource.Table1
               where t.Manager == userId && t.Profile != null
               select t.Profile).ToList();

为什么会出现以下错误：

Error   4   Cannot implicitly convert type 'System.Collections.Generic.List<System.Guid?>' to 'System.Collections.Generic.List<System.Guid>'
