How can I color the cell of datagrid with excel in .net core project
问题
在我的.NET Core项目中，我有一个数据表格。我想根据内容对某些列进行着色。我创建了数据表格然后解析了数据。
DataTable dt = new();
dt.Columns.Add("Status");
dt.Columns.Add("Base");
dt.Columns.Add("First Date");
dt.Columns.Add("Second Date");
dt.Columns.Add("Failure Mode");
dataAll.ForEach(row =>
{
dt.Rows.Add(
row.status,
row.partBase,
row.pcaDate,
row.icaDate,
row.failureMode
);
});
我想要更改状态列的颜色。例如，如果状态等于R，我想将该单元格颜色设置为红色。如何着色数据表格单元格。以下是如何导出到Excel的方式：
using XLWorkbook wb = new();
// 创建数据表格
DataTable dt = MapDataToExcel(response.Result.ToList());
// 添加为工作表
wb.Worksheets.Add(dt, "Rapor");
// 将其保存为文件，然后将其流式传输给用户
using MemoryStream stream = new MemoryStream();
wb.SaveAs(stream);
return File(stream.ToArray(), "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "Rapor.xlsx");
请注意，如何着色数据表格单元格并不在您提供的代码中。要实现此功能，您需要使用Excel库或工具，例如EPPlus，来打开Excel文件并根据条件着色单元格。这部分的代码不包含在您的示例中。
英文:
I have a datatable in my .net core project. I want to color certain column according to the content. I created the datatable and then parsed the data.
DataTable dt = new();
dt.Columns.Add("Status");
dt.Columns.Add("Base");
dt.Columns.Add("First Date");
dt.Columns.Add("Second Date");
dt.Columns.Add("Failure Mode");
dataAll.ForEach(row =>
{
dt.Rows.Add(
row.status,
row.partBase,
row.pcaDate,
row.icaDate,
row.failureMode
);
});
I want to change the color of the status column. For example to color this cell red if the status is equal to R. How can I color the Datatable cell.This is how I export with Excel;
using XLWorkbook wb = new();
// create data table
DataTable dt = MapDataToExcel(response.Result.ToList());
// add as worksheet
wb.Worksheets.Add(dt, "Rapor");
// save it as a file then stream it to the user
using MemoryStream stream = new MemoryStream();
wb.SaveAs(stream);
return File(stream.ToArray(), "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "Rapor.xlsx");

我已经假设状态字段是一个布尔值。您可以将此方法包含在您的代码片段中，并根据您自己的定义更改条件。
private void DataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
bool status = Convert.ToBoolean(e.Row.Cells["Status"].Value);
if (status)
{
e.CellStyle.BackColor = Color.Green;
}
else
{
e.CellStyle.BackColor = Color.Red;
}
}
英文:
I have assumed that the status field is a boolen value. You can include this method in your code fragment and change the condition according to your own definition.
private void DataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
bool status = Convert.ToBoolean(e.Row.Cells["Status"].Value);
if (status)
{
e.CellStyle.BackColor = Color.Green;
}
else
{
e.CellStyle.BackColor = Color.Red;
}
}

for (int i = 2; i < dataCount; i++)
{
foreach (var item in wb.Worksheets)
{
var objPage2 = item.Cell(i, 1).GetString();
if (objPage2 == "R") { item.Cell(i, 1).Style.Fill.BackgroundColor = XLColor.Red; }
if (objPage2 == "G") { item.Cell(i, 1).Style.Fill.BackgroundColor = XLColor.Green; }
if (objPage2 == "Y") { item.Cell(i, 1).Style.Fill.BackgroundColor = XLColor.Yellow; }
}
}
根据特定列的值检查并根据其值进行着色。
英文:
for (int i = 2; i < dataCount; i++)
{
foreach (var item in wb.Worksheets)
{
var objPage2 = item.Cell(i, 1).GetString();
if (objPage2 == "R") { item.Cell(i, 1).Style.Fill.BackgroundColor = XLColor.Red; }
if (objPage2 == "G") { item.Cell(i, 1).Style.Fill.BackgroundColor = XLColor.Green; }
if (objPage2 == "Y") { item.Cell(i, 1).Style.Fill.BackgroundColor = XLColor.Yellow; }
}
}
Check the value of the specific column and color them depending on value
