1.创建Workbook和Worksheet

Workbook wb = new Workbook();

wb.Worksheets.Clear();

wb.Worksheets.Add("New Worksheet1");//New Worksheet1是Worksheet的name

Worksheet ws = wb.Worksheets[0];

如果直接用下边两句则直接使用默认的第一个Worksheet:

Workbook wb = new Workbook();

Worksheet ws = wb.Worksheets[0];

2.给Cell赋值设置背景颜色并加背景色:cell1

Cell cell = ws.Cells[0, 0]; 

cell.PutValue("填充"); //必须用PutValue方法赋值 

cell.Style.ForegroundColor = Color.Yellow; 

cell.Style.Pattern = BackgroundType.Solid; 

cell.Style.Font.Size = 10; 

cell.Style.Font.Color = Color.Blue; 

//自定义格式: 

cell.Style.Custom = "ddd, dd mmmm 'yy"; 

//旋转字体: 

cell.Style.Rotation = 90;

3.设置Range并赋值加Style range1

int styleIndex = wb.Styles.Add(); 

Style style = wb.Styles[styleIndex]; 

style.ForegroundColor = Color.Yellow; 

style.Pattern = BackgroundType.Solid; 

style.Font.Size = 10;  

//从Cells[0,0]开始创建一个2行3列的Range 

Range range = ws.Cells.CreateRange(0, 0, 2, 3); 

Cell cell = range[0, 0]; 

cell.Style.Font = 9; 

range.Style = style; 

range.Merge();

注意Range不能直接设置Style.必须先定义style再将style赋给Style.其他设置和Cell基本一致.Range的Style会覆盖Cell定义的Style.另外必须先赋值再传Style.否则可能不生效。

4.使用Formula:

ws.Cells[0,0].PutValue(1);

ws.Cells[1,0].PutValue(20);

ws.Cells[2,0].Formula="SUM(A1:B1)";

wb.CalculateFormula(true);

Save Excel文件的时候必须调用CalculateFormula方法计算结果。

5.插入图片:

string imageUrl = System.Web.HttpContext.Current.Server.MapPath("~/images/log_topleft.gif");

ws.Pictures.Add(10, 10, imageUrl);

6.使用Validations: 

Cells cells = ws.Cells; 

cells[12, 0].PutValue("Please enter a number other than 0 to 10 in B1 to activate data validation:"); 

cells[12, 0].Style.IsTextWrapped = true; 

cells[12, 1].PutValue(5); 

Validations validations = totalSheet.Validations;

Validation validation = validations[validations.Add()]; 

//Set the data validation type

validation.Type = ValidationType.WholeNumber;

//Set the operator for the data validation

validation.Operator = OperatorType.Between;

//Set the value or expression associated with the data validation

validation.Formula1 = "0";

//the value or expression associated with the second part of the data validation

validation.Formula2 = "10";

validation.ShowError = true;

//Set the validation alert style

validation.AlertStyle = ValidationAlertType.Information;

//Set the title of the data-validation error dialog box

validation.ErrorTitle = "Error";

//Set the data validation error message

validation.ErrorMessage = " Enter value between 0 to 10";

//Set the data validation input message

validation.InputMessage = "Data Validation using Condition for Numbers";

validation.IgnoreBlank = true;

validation.ShowInput = true;

validation.ShowError = true;

//设置Validations的区域，因为现在要Validations的位置是12,1，所以下面设置对应的也要是12,1

 

CellArea cellArea; 

cellArea.StartRow = 12; 

cellArea.EndRow = 12; 

cellArea.StartColumn = 1; 

cellArea.EndColumn = 1; 

validation.AreaList.Add(cellArea);

 
/* 要注意 的地方Validations 也是和Range的Style一样，要新增的，否则不生效 */

举例：

引用：Aspose.Cells.DLL 到项目中

using Aspose.Cells;

public class OperateExcel

{

        /// 导出的文件保存到这里

        private static string ExportFilesPath = System.Configuration.ConfigurationManager.AppSettings["exportFilesPath"].ToString();

        /// 将DataTable生成Excel

        public static string ExportToExcel(DataTable dtList, string fileName)

        {

            //这里是利用Aspose.Cells.dll 生成excel文件的

            string pathToFiles = System.Web.HttpContext.Current.Server.MapPath(ExportFilesPath);

            string etsName = ".xlsx";

            //获取保存路径

            string path = pathToFiles + fileName + etsName;

            Workbook wb = new Workbook();

            Worksheet ws = wb.Worksheets[0];

            Cells cell = ws.Cells;

            //设置行高

            //cell.SetRowHeight(0, 20);

            //表头样式

            Style stHeadLeft = wb.Styles[wb.Styles.Add()];

            stHeadLeft.HorizontalAlignment = TextAlignmentType.Left;       //文字居中

            stHeadLeft.Font.Name = "宋体";

            stHeadLeft.Font.IsBold = true;                                 //设置粗体

            stHeadLeft.Font.Size = 14;                                     //设置字体大小

            Style stHeadRight = wb.Styles[wb.Styles.Add()];

            stHeadRight.HorizontalAlignment = TextAlignmentType.Right;       //文字居中

            stHeadRight.Font.Name = "宋体";

            stHeadRight.Font.IsBold = true;                                  //设置粗体

            stHeadRight.Font.Size = 14;                                      //设置字体大小

            //内容样式

            Style stContentLeft = wb.Styles[wb.Styles.Add()];

            stContentLeft.HorizontalAlignment = TextAlignmentType.Left;

            stContentLeft.Font.Size = 10;

            Style stContentRight = wb.Styles[wb.Styles.Add()];

            stContentRight.HorizontalAlignment = TextAlignmentType.Right;

            stContentRight.Font.Size = 10;

            //赋值给Excel内容

            for (int col = 0; col < dtList.Columns.Count; col++)

            {

                Style stHead = null;

                Style stContent = null;

                //设置表头

                string columnType = dtList.Columns[col].DataType.ToString();

                switch (columnType.ToLower())

                {

                    //如果类型是string，则靠左对齐(对齐方式看项目需求修改)

                    case "system.string":

                        stHead = stHeadLeft;

                        stContent = stContentLeft;

                        break;

                    default:

                        stHead = stHeadRight;

                        stContent = stContentRight;

                        break;

                }

                putValue(cell, dtList.Columns[col].ColumnName, 0, col, stHead);

                for (int row = 0; row < dtList.Rows.Count; row++)

                {

                    putValue(cell, dtList.Rows[row][col], row + 1, col, stContent);

                }

            }

            wb.Save(path);

            return ExportFilesPath + fileName + etsName;

        }

        //填充数据到excel中

        private static void putValue(Cells cell, object value, int row, int column, Style st)

        {       

            cell[row, column].PutValue(value);

            cell[row, column].SetStyle(st);

        }
}

//调用上面方法（MVC）：

public FileResult FileExportExcel()

{

            string filePath = OperateExcel.ExportToExcel(getData(), DateTime.Now.ToString("yyyyMMddHHmmss"));

            return File(Server.MapPath(filePath), "application/ms-excel", Path.GetFileName(filePath));
}
