将数据从文件复制到数据存储

Question

是否可以导出以插入查询？

我有一个疑问，在页面（http://www.filehelpers.net/）中的图像“高级用途的库：将数据从文件复制到数据存储”但我找不到信息，并知道我是否可以导出到SQL。

这应该工作：

[DelimitedRecord("|")] 
public class CustomersVerticalBar 
{ 
    public string CustomerID; 
    public string CompanyName; 
    public string ContactName; 
    public string ContactTitle; 
    public string Address; 
    public string City; 
    public string Country; 
} 

class Program 
{ 
    private static string GetInsertSqlCust(object record) 
    { 
     CustomersVerticalBar obj = (CustomersVerticalBar)record; 

     return String.Format("INSERT INTO Customers (Address, City, CompanyName, ContactName, ContactTitle, Country, CustomerID) " + 
       " VALUES ('{0}' , '{1}' , '{2}' , '{3}' , '{4}' , '{5}' , '{6}' ); ", 
       obj.Address, 
       obj.City, 
       obj.CompanyName, 
       obj.ContactName, 
       obj.ContactTitle, 
       obj.Country, 
       obj.CustomerID 
      ); 
    } 

    static void Main(string[] args) 
    { 
     SqlServerStorage storage = new SqlServerStorage(typeof(CustomersVerticalBar)); 

     storage.ServerName = "MYSERVER"; 
     storage.DatabaseName = "Northwind"; 

     // Comment this for Windows Auth 
     storage.UserName = "shamp00"; 
     storage.UserPass = "whatever"; 

     storage.InsertSqlCallback = new InsertSqlHandler(GetInsertSqlCust); 

     storage.InsertRecords(CommonEngine.ReadFile(typeof(CustomersVerticalBar), "infile.txt")); 

     Console.ReadKey(); 
    } 
} 

我敢肯定，曾经有一些这方面的文档 - 他们似乎从最新的网站缺少的。您可以查看FileHelpers源代码中的单元测试some more examples。
