假设我有两个内部具有父子关系的表。
个人资料:
报告:
ProfileReport:
和UserProfile:
我的方案是首先找到用户的个人资料列表,然后找到用户个人资料的报告树。 我到目前为止尝试的是:
// Load excel data in to sql database
private void BtnRefreshDatabase_Click(object sender, EventArgs e)
{
OpenFileDialog ope = new OpenFileDialog();
//ope.Filter = "Excel File| *.xls ";
if (ope.ShowDialog() == DialogResult.Cancel)
return;
FileStream stream = new FileStream(ope.FileName, FileMode.Open,FileAccess.Read);
IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
DataSet result = excelReader.AsDataSet();
LinqToEntermedDatabaseDataContext conn = new LinqToEntermedDatabaseDataContext();
// System.Data.Linq.Mapping.ColumnAttribute(storarge="Artikel",DbType="uniquIdentifier NOT NULL",IsPrimaryKey=true) volgens voorbeeld website stackoverflow
foreach (DataTable table in result.Tables)
{
foreach (DataRow dr in table.Rows)
{
TableOption addtable = new TableOption()
{
Artikel = Convert.ToString(dr[0]),
Discription = Convert.ToString(dr[1]),
Extra1 = Convert.ToString(dr[2]),
Extra2 = Convert.ToString(dr[3]),
Kosts = Convert.ToDecimal(dr[4])
};
conn.TableOptions.InsertOnSubmit(addtable);
}
conn.SubmitChanges();
excelReader.Close();
stream.Close();
MessageBox.Show("Database ok");
}
}
但我无法让报告树正确。有没有办法实现查找配置文件树,然后找到与配置文件树用户对应的报告树?
