概述

本篇將通過導出學生成績的示例演示“使用ExcelReport導出Excel”的步驟。

 

示例（導出學生成績明細）

步驟一：設計Excel模板

首先，使用Excel軟件設計模板（我沒有安裝MSOffice，用LibreOffice Calc做的演示）。在模板中要填充數據的位置用$[ParameterName]代替。

步驟二：生成模板填充規則文件

使用模板填充規則文件生成工具（ERTool）為步驟一設計的Excel模板生成填充規則文件。

步驟三：為模板填充數據

 

實現代碼(導出到本地)：

//實例化一個參數容器，並加載模板填充規則文件
ParameterCollection collection = new ParameterCollection();
collection.Load(@"Template\Template.xml");

//實例化一個元素格式化器列表
List<ElementFormatter> formatters = new List<ElementFormatter>();
formatters.Add(new CellFormatter(collection["GradeDetail", "Dept"], "某某學院"));   //添加一個單元格格式化器
formatters.Add(new CellFormatter(collection["GradeDetail", "Class"], "某某班級"));
formatters.Add(new CellFormatter(collection["GradeDetail", "StudNo"], "2009*****"));
formatters.Add(new CellFormatter(collection["GradeDetail", "StudName"], "韓兆新"));
formatters.Add(new CellFormatter(collection["GradeDetail", "ExportDate"], DateTime.Now));

List<GradeInfo> gradeInfoList = new List<GradeInfo>();
gradeInfoList.Add(new GradeInfo() { CGPA = 18, CourseID = "KC-0001", CourseName = "高等數學", CourseType = "理論課", Credit = 6, EvaluationMode = "考試", GainCredit = 6, GPA = 3, Grade = 86, StudyNature = "初修", Type = "必修課" });
gradeInfoList.Add(new GradeInfo() { CGPA = 2, CourseID = "KC-0002", CourseName = "計算機應用基礎", CourseType = "理論課", Credit = 2, EvaluationMode = "考試", GainCredit = 2, GPA = 1, Grade = 93, StudyNature = "初修", Type = "必修課" });
gradeInfoList.Add(new GradeInfo() { CGPA = 9, CourseID = "KC-0003", CourseName = "C程序設計", CourseType = "理論課", Credit = 3, EvaluationMode = "考試", GainCredit = 3, GPA = 3, Grade = 97, StudyNature = "初修", Type = "必修課", Remark = "備注信息" });

//添加一個Table格式化器
formatters.Add(new TableFormatter<GradeInfo>(collection["GradeDetail", "CourseID"].X, gradeInfoList,
    new TableColumnInfo<GradeInfo>(collection["GradeDetail", "CGPA"].Y, t => t.CGPA),
    new TableColumnInfo<GradeInfo>(collection["GradeDetail", "CourseID"].Y, t => t.CourseID),

    new TableColumnInfo<GradeInfo>(collection["GradeDetail", "StudyNature"].Y, t => t.StudyNature),
    new TableColumnInfo<GradeInfo>(collection["GradeDetail", "Type"].Y, t => t.Type)
    ));
//導出文件到本地
Export.ExportToLocal(@"Template\Template.xls", saveFileDlg.FileName,
    new SheetFormatterContainer("GradeDetail", formatters));
