-- 从ListView中导出Excel报表

关键词：ListView，数据绑定，导入Excel，导出Excel

WinForm中用来显示数据时我们常用ListView，有时我们需要将数据从Excel表格导入到系统中，有时我们也会将ListView中的数据导出至xcel，今天我们用一个小程序来练习一下这两个功能。

首先建一个WinForm的项目，在窗口中添加一个toolStrip,在其中添加两个button，一个用于导入Excel，一个用于导出Excel。再添加一个Listview。如图所示。



public partial class AceyOffice : Form

{

public AceyOffice()

{

InitializeComponent();

InitLvPart("StudentInfo");

}

//初始化Listview的显示列

private void InitLvPart(string customflg)

{

if (customflg == "StudentInfo")

{

this.listView1.Clear();

this.listView1.Columns.Add("姓名");

this.listView1.Columns.Add("学号");

this.listView1.Columns.Add("数学");

this.listView1.Columns.Add("语文");

this.listView1.Columns.Add("英语");

this.listView1.Columns.Add("总分");

}

}

//导入Excel

private void toolStripButton1_Click(object sender, EventArgs e)

{

OpenFileDialog ofdlg = new OpenFileDialog();

ofdlg.Filter = "(*.xls)|*.xls";

ofdlg.Title = "请选择需导入Excel文件";

if (ofdlg.ShowDialog() == DialogResult.OK)

{

string filepath = ofdlg.FileName;

IWorkbook workbook = ExcelxApplication.Open(filepath);

IWorksheet worksheet = workbook.Worksheets[0];

List<List<string>> studentsinfo = new List<List<string>>();

//获取Excel表括格中的所有信息

for (int i = 1; i < worksheet.Rows.Count;i++ )

{

if (worksheet.Cells[i, 0].Value != null)

{

List<string> student = new List<string>();

string studentname = worksheet.Cells[i, 0].Value.ToString();

student.Add(studentname);

string studentnumber = worksheet.Cells[i, 1].Value.ToString();

student.Add(studentnumber);

string math = worksheet.Cells[i, 2].Value.ToString();

student.Add(math);

string chinese = worksheet.Cells[i, 3].Value.ToString();

student.Add(chinese);

string english = worksheet.Cells[i, 4].Value.ToString();

student.Add(english);

string total = worksheet.Cells[i, 5].Value.ToString();

student.Add(total);

studentsinfo.Add(student);

}

else

break;

}

//绑定ListView

for(int j=0;j<studentsinfo.Count;j++)

{

ListViewItem item = new ListViewItem();

item.Text = studentsinfo[j][0];

item.SubItems.Add(studentsinfo[j][1]);

item.SubItems.Add(studentsinfo[j][2]);

item.SubItems.Add(studentsinfo[j][3]);

item.SubItems.Add(studentsinfo[j][4]);

item.SubItems.Add(studentsinfo[j][5]);

this.listView1.Items.Add(item);

}

}

}

//导出Excel

private void toolStripButton2_Click(object sender, EventArgs e)

{

IWorkbook workbook = ExcelxApplication.CreateWorkbook();

IWorksheet worksheet = workbook.Worksheets[0];

worksheet.Cells[0, 0].Value = "姓名";

worksheet.Cells[0, 1].Value = "学号";

worksheet.Cells[0, 2].Value = "语文";

worksheet.Cells[0, 3].Value = "数学";

worksheet.Cells[0, 4].Value = "英语";

worksheet.Cells[0, 5].Value = "总分";

for (int i = 0; i < this.listView1.Items.Count; i++)

{

worksheet.Cells[i + 1, 0].Value = this.listView1.Items[i].SubItems[0].Text;

worksheet.Cells[i + 1, 1].Value = this.listView1.Items[i].SubItems[1].Text;

worksheet.Cells[i + 1, 2].Value = this.listView1.Items[i].SubItems[2].Text;

worksheet.Cells[i + 1, 3].Value = this.listView1.Items[i].SubItems[3].Text;

worksheet.Cells[i + 1, 4].Value = this.listView1.Items[i].SubItems[4].Text;

worksheet.Cells[i + 1, 5].Value = this.listView1.Items[i].SubItems[5].Text;

}

workbook.SaveAs("C:\\StudentInfo.xls", FileFormat.Excel97To2003);

}

}
