如何在Datetimepicker中提取给定日期到Currentdate的数据
||
我有很多文件夹，并且有很多日期不同的数据文件。现在，如果我从DatePicker中选择日期，我的代码将提取数据并提取日期，并将该日期作为名称保存到txt文件（例如
YYYYMMDD.txt
20110131.txt
private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
{
DateTime dt = dateTimePicker1.Value;
txtSelectedDate.Text = dt.ToString(\"yyyyMMdd\");
selectedDate = txtSelectedDate.Text;
}
private void button2_Click(object sender, EventArgs e)
{
string DayBgSpot = \"E:\\\\Folder\";
string DayBgSpotDestination = \"E:\\\\Folder1\";
int DT = int.Parse(txtSelectedDate.Text);
FileReader Reader = new FileReader();
FileReader Reader1 = new FileReader();
Reader.OpenDirectory(DayBgSpot);
Reader.ReadNaster();
string path = DayBgSpotDestination + \"\\\\\" + txtSelectedDate.Text + \".txt\";
StreamWriter Strwriter = new StreamWriter(path);
try
{
while (Reader.iMaRecordsLeft > 0)
{
string SecName = Reader.sMaSecName;
string Symbol = Reader.sMaSecSymbol;
Symbol = prefix + Symbol;
int abc = 0;
Reader.OpenSecurityByName(Reader.sMaSecName);
if (Reader.iSeRecords > 0)
{
while (Reader.iSeRecordsLeft > 0)
{
Reader.ReadDay();
float O = Reader.dSeo;
float H = Reader.dSeh;
float L = Reader.dSel;
float C = Reader.dSec;
double V = Reader.dSeV;
double OI = Reader.dSrest;
string T = Reader.iSeTime.ToString();
string D = Reader.iSeDate.ToString();
if (int.Parse(D) == DT)
{
string a = string.Concat(SecName, \",\", Symbol, \",\", D, \",\", T, \",\", O, \",\", H, \",\", L, \",\", C, \",\", V, \",\", OI);
if (SecName != \"\" && V != 0)
{
Strwriter.WriteLine(a);
}
}
}
}
abc++;
Reader.ReadNaster();
}
Reader.CloseDirectory();
Strwriter.Close();
Strwriter.Dispose();
}
catch
{
}
}

很缴
DateTime stdate = Datetimepicker1.value; while (stdate <= DateTime.Now) { txtSelectedDate.Text = stdate.ToString(\"yyyyMMdd\"); selectedDate = txtSelectedDate.Text; /* Here use your existing code as it is */ ............ ......... stdate = stdate.AddDays (1); // It will get next date till present }
