WPF和EXCEL的交互

 

      日常工作中我们经常需要和office打交道，我们的程序也可能需要将数据导出为excel进行再次处理。在WPF中我觉得比较方便的和excel进行交互的2个方式如下：

 

　　写入excel：

System.Windows.Forms.SaveFileDialog sd=new System.Windows.Forms.SaveFileDialog();
sd.Filter="Excel 2003 文档|*.xls";
if(sd.ShowDialog()==System.Windows.Forms.DialogResult.OK)
{
    FileStream fs=new FileStream(sd.FileName,FileMode.Create,FileAccess.Write);
    StreamWriter sw=new StreamWriter(fs,Encoding.Default);
    string line="";
    //写入列标题
    for (int i = 0; i < datamain.Columns.Count; i++)
    {
        line += datamain.Columns[i].Header.ToString() + "\t";
    }
    sw.WriteLine(line);
    for (int j = 0; j < datamain.Items.Count; j++)
    {

        Statresult dt = datamain.Items[j] as Statresult;
        line = dt.Client + "\t" + dt.Total + "\t" + dt.Receive + "\t" + dt.Rates + "\t" + dt.Inspection + "\t" + dt.Bugnum + "\t" + dt.Qualified + "\t";
        sw.WriteLine(line);

    }
    //关闭流
    sw.Close();
    fs.Close();
    MessageBox.Show("数据已经成功导出!","注意",MessageBoxButton.OK,MessageBoxImage.Information);
}

　　读取excel:

//以oledb方式连接excel文件并将混合型作为文本型读取
strConn = "Provider=Microsoft.Jet.  OLEDB.4.0;Data Source=C:\\Erp1912.xls;Extended   Properties='Excel8.0;HDR=Yes;IMEX=1'";  
OleDbConnection conn = new OleDbConnection(strCon);
//将工作表作为数据表
string sql = "SELECT * FROM [Sheet1$]";
OleDbDataAdapter adp = new OleDbDataAdapter(sql,conn);
DataSet myDataSet = new DataSet();
adp.Fill(myDataSet,"[Sheet1$]");
