Aspose Cells使用总结

Aspose Cells使用总结

使用Aspose.Cells的基础知识整理

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 = \;

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=\; 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(\og_topleft.gif\);

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

6.使用Validations:

validations1

Cells cells = ws.Cells;

cells[12, 0].PutValue(\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 = \;

//the value or expression associated with the second part of the data validation validation.Formula2 = \;

validation.ShowError = true; //Set the validation alert style

validation.AlertStyle = ValidationAlertType.Information; //Set the title of the data-validation error dialog box validation.ErrorTitle = \;

//Set the data validation error message

validation.ErrorMessage = \; //Set the data validation input message

validation.InputMessage = \; 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:
