我想知道是否有人使用过DocumentFormat.OpenXml，因为我在使用DocumentFormat.Spreadsheet的条件下对单元格着色有问题。
现在我可以第一次创建颜色，但我需要打开相同的Excel工作表，并根据我需要为特定单元格着色的条件。例如。如果单元格D1为黄色，则D2可以为绿色或黄色。
e.g。
Name IpAddress Region Details
Switch 10.1.1.1 EMEA Based on Condition the cell would be coloured
Switch 10.1.1.2 AMER Based on Condition the cell would be coloured
Switch 10.1.1.3 APAC Based on Condition the cell would be coloured
Switch 10.1.1.2 AMER Based on Condition the cell would be coloured
Switch 10.1.1.2 AMER Based on Condition the cell would be coloured
我每次都在写每一行，当我想打开现有的excel表时，我会传递值，即_valuecolour并根据其值，它将为特定单元格着色以及其他单元格的对齐。
我使用了以下代码。
public static bool InsertRowExcel(string filepath, string _sb, string _switchinput)
{
int i = 0;
string[] _arr = _switchinput.Split(',');
bool bl = false;
int k = 0;
try
{
using (SpreadsheetDocument myDoc = SpreadsheetDocument.Open(filepath, true))
{
//Get workbookpart
WorkbookPart workbookPart = myDoc.WorkbookPart;
WorkbookStylesPart stylePart = workbookPart.WorkbookStylesPart;
Row row = new Row();
//then access to the worksheet part
IEnumerable<WorksheetPart> worksheetPart = workbookPart.WorksheetParts;
foreach (WorksheetPart WSP in worksheetPart)
{
//find sheet data
IEnumerable<SheetData> sheetData = WSP.Worksheet.Elements<SheetData>();
// Iterate through every sheet inside Excel sheet
foreach (SheetData SD in sheetData)
{
IEnumerable<Row> rows = SD.Elements<Row>(); // Get the row IEnumerator
i = (rows.Count()); // Will give you the count of rows
do
{ row = new Row();
row.Append(
ConstructCell(_arr[0], CellValues.String),
ConstructCell(_arr[1], CellValues.String),
ConstructCell(_arr[2], CellValues.String),
ConstructCell(_sb, CellValues.String,2U)
);
}
while (k > 0);
/* HERE I NEED TO ADD STYLE TO THE CELL. */
}
}
bl = true;
}
}
catch (Exception ex)
{
bl = false;
throw ex;
}
return bl;
}
private static Stylesheet GenerateStylesheet(bool _valuecolour)
{
Stylesheet styleSheet = null;
Fills fills = new Fills();
if (_valuecolour)
{
fills = new Fills(
new Fill(new PatternFill() { PatternType = PatternValues.None }), // Index 0 - default
new Fill(new PatternFill() { PatternType = PatternValues.Gray125 }), // Index 1 - default
new Fill(new PatternFill(new ForegroundColor { Rgb = new HexBinaryValue() { Value = "FFFFFF00" } })
{ PatternType = PatternValues.Solid })
);
}
else
{

new Fill(new PatternFill() { PatternType = PatternValues.None }), // Index 0 - default
new Fill(new PatternFill() { PatternType = PatternValues.Gray125 }), // Index 1 - default
new Fill(new PatternFill(new ForegroundColor { Rgb = new HexBinaryValue() { Value = "008000" } })
{ PatternType = PatternValues.Solid }) // Index 2 - body
);
}
CellFormats cellFormats = new CellFormats(
new CellFormat(), // default
new CellFormat(new Alignment() { Horizontal = HorizontalAlignmentValues.Left, Vertical = VerticalAlignmentValues.Top, WrapText = true })
{ FontId = 0, FillId = 0, BorderId = 1, ApplyAlignment = true },
new CellFormat(new Alignment() { Horizontal = HorizontalAlignmentValues.Left, Vertical = VerticalAlignmentValues.Top, WrapText = true }){ FontId = 1, FillId = 2, BorderId = 1, ApplyFill = true }); // header
styleSheet = new Stylesheet(fills, cellFormats);
return styleSheet;
}
private static Cell ConstructCell(string value, CellValues dataType,uint styleIndex = 0)
{
return new Cell()
{
CellValue = new CellValue(value),
DataType = new EnumValue<CellValues>(dataType),
StyleIndex = styleIndex
};
}
答案 0 :(得分：0)
以下是按预期工作的代码
在这里输入代码
