Excel添加红绿灯

我创build一个基于DataSet的Excel文件，我想添加一个红绿灯的列。

红绿灯：

 int trafficCollor = 1; if (trafficCollor == 1) { DataRow NR = DT.NewRow(); NR[0] = ""; //add string with the code for the Excel traffic light yellow } if (trafficCollor < 1) { DataRow NR = DT.NewRow(); NR[0] = ""; //add string with the code for the Excel traffic light green } if (trafficCollor > 1) { DataRow NR = DT.NewRow(); NR[0] = ""; //add string with the code for the Excel traffic light red } 

Excel如何创build：

 //Create an Excel application instance Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application(); Microsoft.Office.Interop.Excel.Workbook excelWorkBook = excelApp.Application.Workbooks.Add(); Microsoft.Office.Interop.Excel._Worksheet worksheet = null; excelApp.Visible = false; worksheet = excelWorkBook.ActiveSheet; //set headers for (int i = 1; i < DGV.Columns.Count + 1; i++) { worksheet.Cells[1, i] = DGV.Columns[i - 1].HeaderText; } createList(worksheet, DGV); //Create excel with the choosen name Worksheet sheet1 = excelWorkBook.Worksheets[1]; worksheet.Name = fileName; 

如果您有任何build议来存档这样的东西，让我知道！

以下是我快速编写的示例代码，演示如何在条件格式中使用“交通灯”。 请改变它以适应您的需求。

 using System; using System.Windows.Forms; using Excel = Microsoft.Office.Interop.Excel; Namespace WindowsFormsApplication2 { public partial class Form1 : Form { Public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { Excel.Application xlexcel; Excel.Workbook xlWorkBook; Excel.Worksheet xlWorkSheet; object misValue = System.Reflection.Missing.Value; xlexcel = new Excel.Application(); xlWorkBook = xlexcel.Workbooks.Add(misValue); xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1); xlexcel.Visible = true; //add data xlWorkSheet.Cells[1, 1] = 1; xlWorkSheet.Cells[2, 1] = 2; xlWorkSheet.Cells[3, 1] = 3; xlWorkSheet.Cells[4, 1] = 4; Excel.Range MyRange = xlWorkSheet.get_Range("A1", "A4"); MyRange.FormatConditions.AddIconSetCondition(); MyRange.FormatConditions.Item (MyRange.FormatConditions.Count).SetFirstPriority(); MyRange.FormatConditions.Item(1).ReverseOrder = false; MyRange.FormatConditions.Item(1).ShowIconOnly = false; MyRange.FormatConditions.Item(1).IconSet = xlWorkBook.IconSets[Excel.XlIconSet.xl3TrafficLights2]; MyRange.FormatConditions.Item(1).IconCriteria(2).Type = Excel.XlConditionValueTypes.xlConditionValuePercent; MyRange.FormatConditions.Item(1).IconCriteria(2).Value = 33; MyRange.FormatConditions.Item(1).IconCriteria(2).Operator = 7; MyRange.FormatConditions.Item(1).IconCriteria(3).Type = Excel.XlConditionValueTypes.xlConditionValuePercent; MyRange.FormatConditions.Item(1).IconCriteria(3).Value = 67; MyRange.FormatConditions.Item(1).IconCriteria(3).Operator = 7; // Rest of the code } } }
