使用Aspose.Cells实现后台输出Excel报表（C#）
使用Aspose.Cells实现后台输出Excel报表
这项任务的需求简单明了，将前期在网页中的报表作为Excel工作簿输出。其中包含较多的sheet工作表,需要设置较复杂的颜色和格式。
1.获得想要输出的DataTable
DataTable tempdatatable = new DataTable();
try {
//获取DataTable数据
tempdatatable = GetDataTable(date, cities, paramlist[i], "是");
}
catch (Exception e)
{
Logger.Error(e);
}2.初始化Workbook
Workbook workbook = new Workbook();
//标题样式
Style titlestyle = workbook.Styles[workbook.Styles.Add()];//新增样式
titlestyle.ForegroundColor = Color.FromArgb(241, 241, 241);
titlestyle.Pattern = BackgroundType.Solid;
titlestyle.HorizontalAlignment = TextAlignmentType.Center;//文字居中
titlestyle.VerticalAlignment = TextAlignmentType.Center;//上下居中
//titlestyle.Font.Name = "宋体";//文字字体
titlestyle.Font.Size = 10;//文字大小
titlestyle.Font.IsBold = true;//粗体
titlestyle.Borders[BorderType.LeftBorder].LineStyle = CellBorderType.Thin;
titlestyle.Borders[BorderType.RightBorder].LineStyle = CellBorderType.Thin;
titlestyle.Borders[BorderType.TopBorder].LineStyle = CellBorderType.Thin;
titlestyle.Borders[BorderType.BottomBorder].LineStyle = CellBorderType.Thin;
titlestyle.Borders.SetColor(Color.FromArgb(160, 161, 161));
titlestyle.IsTextWrapped = true;
//内容样式
Style contentstyle = workbook.Styles[workbook.Styles.Add()];
//contentstyle.Font.Name = "宋体";//文字字体
contentstyle.Font.Size = 10;//文字大小
contentstyle.Font.IsBold = true;//粗体
contentstyle.HorizontalAlignment = TextAlignmentType.Center;//文字居中
contentstyle.VerticalAlignment = TextAlignmentType.Center;//上下居中
contentstyle.Borders[BorderType.LeftBorder].LineStyle = CellBorderType.Thin;
contentstyle.Borders[BorderType.RightBorder].LineStyle = CellBorderType.Thin;
contentstyle.Borders[BorderType.TopBorder].LineStyle = CellBorderType.Thin;
contentstyle.Borders[BorderType.BottomBorder].LineStyle = CellBorderType.Thin;
contentstyle.Borders.SetColor(Color.FromArgb(160, 161, 161));
//告警样式——红色背景
Style contenredtstyle = workbook.Styles[workbook.Styles.Add()];
//contenredtstyle.Font.Name = "宋体";//文字字体
contenredtstyle.Font.Size = 10;//文字大小
contenredtstyle.Font.IsBold = true;//粗体
contenredtstyle.HorizontalAlignment = TextAlignmentType.Center;//文字居中
contenredtstyle.VerticalAlignment = TextAlignmentType.Center;//上下居中
contenredtstyle.ForegroundColor = Color.FromArgb(230, 32, 32);
contenredtstyle.Pattern = BackgroundType.Solid;
//绿色字体
Style topthreegreen = workbook.Styles[workbook.Styles.Add()];
topthreegreen.Font.Color = Color.FromArgb(0, 255, 0);
//topthreegreen.Font.Name = "宋体";//文字字体
topthreegreen.Font.Size = 10;//文字大小
topthreegreen.Font.IsBold = true;//粗体
topthreegreen.HorizontalAlignment = TextAlignmentType.Center;//文字居中
topthreegreen.VerticalAlignment = TextAlignmentType.Center;//上下居中
//红色字体
Style redfont = workbook.Styles[workbook.Styles.Add()];
redfont.Font.Color = Color.Red;
redfont.Font.Size = 10;//文字大小
redfont.Font.IsBold = true;//粗体
redfont.HorizontalAlignment = TextAlignmentType.Center;//文字居中
redfont.VerticalAlignment = TextAlignmentType.Center;//上下居中3.填充数据并设置格式
string filePathBase = ConfigurationManager.AppSettings["File_Path"].ToString() + "\\";
try
{
for (int i = 0; i < paramlist.Length; i++)
{
DataTable tempdatatable = new DataTable();
try
{
//获取DataTable数据
tempdatatable = GetDataTable(date, cities, paramlist[i], "是");
}
catch (Exception e)
{
Logger.Error(e);
}
if (i > 0)
{
workbook.Worksheets.Add();
}
Worksheet worksheet = workbook.Worksheets[i];//
worksheet.Name = paramlist[i];
Cells cells = worksheet.Cells;
int Colnum = tempdatatable.Columns.Count;//表格列数
int Rownum = tempdatatable.Rows.Count;//表格行数
if (Colnum > 0)
{
//设置列头
for (int c = 0; c < Colnum; c++)
{
cells[0, c].PutValue(tempdatatable.Columns[c].ColumnName);
cells[0, c].SetStyle(titlestyle);
cells.SetColumnWidth(c, 15);
cells.SetRowHeight(0, 25);
}
//填入数据 设置style
for (int r = 0; r < Rownum; r++)
{
object lastmonthvalue = tempdatatable.Rows[r][1];
object tmpvalue = null;
cells.SetRowHeight(r + 1, 15);
for (int c = 0; c < Colnum; c++)
{
tmpvalue = tempdatatable.Rows[r][c];
cells[r + 1, c].PutValue(tmpvalue.ToString());
cells[r + 1, c].SetStyle(contentstyle);
if (c >= 4 && r > 1 && r < 16)//只选择第四列之后，第三行与第十六行之间的数据进行门限比对
{
bool iscellerror = CheckCellValue(paramlist[i], lastmonthvalue, tmpvalue);
if (iscellerror)
{//达到标红门限
cells[r + 1, c].SetStyle(contenredtstyle);
}
}
if (c == 3 && r > 1 && r < 15)//排名
{
int ranking = Convert.ToInt32(tmpvalue);
if (ranking <= 3)
{
cells[r + 1, c].SetStyle(topthreegreen);
}
if (ranking >= 11)
{
cells[r + 1, c].SetStyle(contenredtstyle);
}
}
}
}
//列头2 3
for (int c = 0; c < Colnum; c++)
{
cells[1, c].SetStyle(titlestyle);
cells[2, c].SetStyle(titlestyle);
}
cells[18, 0].SetStyle(redfont);//恶化原因说明
worksheet.FreezePanes(1, 4, 1, 4);//冻结前四列 冻结前三行
}
//setColumnWithAuto(worksheet);自动列宽
}
}
catch (Exception ex)
{
Logger.Error(ex);
excelFileInfo.setError("出错", ex.Message, -1);
}4.输出文件
if (excelFileInfo.Data != (object)(-1))
{
string filename = "网络日报问题跟踪\\网络日报问题跟踪表" + date + ".xlsx";
if (!Directory.Exists(filePathBase + "网络日报问题跟踪"))
{
// Create the directory it does not exist.
Directory.CreateDirectory(filePathBase + "网络日报问题跟踪");
}
workbook.Save(filePathBase + filename);
excelFileInfo.setInfo("", filename);
}
return excelFileInfo;*设置自动列宽的方法
void setColumnWithAuto(Worksheet sheet)
{
Cells cells = sheet.Cells;
int columnCount = cells.MaxColumn; //获取表页的最大列数
int rowCount = cells.MaxRow; //获取表页的最大行数
for (int col = 0; col < columnCount; col++)
{
sheet.AutoFitColumn(col, 0, rowCount);
}
for (int col = 0; col < columnCount; col++)
{
cells.SetColumnWidthPixel(col, cells.GetColumnWidthPixel(col) + 30);
}
