使用Aspose.Cells的基础知识整理
转自 http://www.cnblogs.com/kenblove/archive/2009/01/07/1371104.html 这两天用Aspose.Cells构建一个Excel报表,感觉这个组件还比较好用.记录一下常用的使用知识: 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:
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:
formula1
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:
pictures1
string imageUrl = System.Web.HttpContext.Current.Server.MapPath("~/images/log_topleft.gif"); ws.Pictures.Add(10, 10, imageUrl);
6.使用Validations:
validations1
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 */
上边不过是基础中的基础,要了解更多就要自己不断的尝试了.下边奉上帮助文档和DLL: |
