我是新的C#編碼器,我也是Microsoft SQL Server的新成員。我編寫的代碼將使用filehelpers解析來自文件的數據,然後將該數據放入SQL表中。我的問題是它是否可以解析數據,但只將部分字符串放在SQL服務器中。例如,這裏是我的代碼:使用C將僅字符串的一部分插入到SQL數據庫中#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using FileHelpers;
using System.Data.SqlClient;
using System.IO;
namespace OnQ_prototype
{
class Report
{
[DelimitedRecord("\t")]
[IgnoreEmptyLines()]
public class ColumnReportNames
{
public String textbox22;
public String textbox29;
public String textbox24;
public String textbox23;
public String PSFullAcct;
public String AccountDescription;
public String BusDateAmount;
public String ThisPTDAmount;
public String LastPTDAmount;
public String ThisYTDAmount;
public String LastYTDAmount;
public String BusDatePctAvail;
public String ThisPTDPctAvail;
public String LastPTDPctAvail;
public String ThisYTDPctAvail;
public String LastYTDPctAvail;
}
static void ProcessFilesCSVFiles(string originalPath, string destinationPath)
{
foreach (var GenesisDirectory in Directory.GetDirectories(originalPath))
{
foreach (var inputFile in Directory.GetFiles(GenesisDirectory, "*.csv"))
{
string lines = inputFile;
FileHelperEngine engine = new FileHelperEngine(typeof(ColumnReportNames));
var records = engine.ReadFile(lines) as ColumnReportNames[];
foreach (var record in records)
{
SqlCommand cmd;
SqlConnection conn;
conn = new SqlConnection("Data Source=hureports01;Initial Catalog=hureports;Integrated Security=True");
conn.Open();
var sqlCommand = string.Format(@"MERGE [OnQReport] AS target USING (select @Property as Property, @Date_of_Report as Date_of_Report, @Percent_Occupancy_PAR as Percent_Occupancy_PAR, @val as {0}) AS source ON (target.Date_of_Report = source.Date_of_Report) WHEN MATCHED THEN UPDATE SET {0}= source.{0} WHEN NOT MATCHED THEN INSERT (Property, Date_of_Report, Percent_Occupancy_PAR, {0}) VALUES (source.Property, source.Date_of_Report, Percent_Occupancy_PAR, source.{0});", column);
cmd = new SqlCommand(sqlCommand, conn);
cmd.Parameters.AddWithValue("@Property", record.textbox24);
cmd.Parameters.AddWithValue("@Date_of_Report", record.textbox23);
cmd.Parameters.AddWithValue("@Percent_Occupancy_PAR", amount2);
cmd.Parameters.AddWithValue("@val", amount);
cmd.ExecuteNonQuery();
conn.Close();
}
所以我添加的一個值是Date_of_Report它位於textbox23。但是,textbox23的價值是商業日期:6/14/2016。有沒有辦法爲它只是把日期Date_of_Report(即擺脫「商務時間」的
歡迎堆棧溢出,請閱讀[如何創建一個最小的,完整的,並且可驗證的示例](http://stackoverflow.com/help/mcve) –
是的,這是一個簡單的編程問題,請goog le「C#字符串解析示例」並嘗試找到的示例。如果遇到您不明白的錯誤,請嘗試將其作爲問題發佈。 –
謝謝。我對編碼非常陌生,但是這對我有很大的幫助 – user6451557
