c# - 使用 Visual Studio 2008 C#/ASP .NET Web 应用程序将 Excel 数据导入 SQL Server 2008

Question

我想知道如何将 excel 文件导入 SQL Server 2008。例如，我有一个文本框、浏览按钮和导入按钮。我将单击浏览并浏览 excel 文件，然后单击导入以插入到数据库中的特定表中 excel 文件中的所有数据（不是创建新表）。有没有人知道这个代码？放在哪里？非常感谢您。:)

Answer 1

我还没有尝试过这个，但我认为它将有两个主要步骤。

1. 您必须创建一个可以打开和读取 Excel 文件内容的函数
   参考：如何在 C# 中打开 Excel 文件？
2. 读取excel文件内容并导入数据库表
   参考： http: //www.codeproject.com/Articles/14528/Generate-SQL-INSERT-commands-programmatically
   创建新表：
   以编程方式创建sql表

希望能给点思路。

Answer 2

你可以试试这个

//代码 ....

Imports System.Data
Imports System.Data.OleDb
Imports System.Data.SqlClient
Imports System.Web.Configuration


    'Declare Variables - Edit these based on your particular situation
    Dim sSQLTable As String = "TempTableForExcelImport"
    Dim sExcelFileName As String = "myExcelFile.xls"
    Dim sWorkbook As String = "[WorkbookName$]"



    'Create our connection strings
    Dim sExcelConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath(sExcelFileName) & ";Extended Properties=""Excel 8.0;HDR=YES;"""
    Dim sSqlConnectionString As String = WebConfigurationManager.ConnectionStrings("MyConnectionString").ToString


'Execute a query to erase any previous data from our destination table
Dim sClearSQL = "DELETE FROM " & sSQLTable
Dim SqlConn As SqlConnection = New SqlConnection(sSqlConnectionString)
Dim SqlCmd As SqlCommand = New SqlCommand(sClearSQL, SqlConn)
SqlConn.Open()
SqlCmd.ExecuteNonQuery()
SqlConn.Close()

'Series of commands to bulk copy data from the excel file into our SQL table
Dim OleDbConn As OleDbConnection = New OleDbConnection(sExcelConnectionString)
Dim OleDbCmd As OleDbCommand = New OleDbCommand(("SELECT * FROM " & sWorkbook), OleDbConn)
OleDbConn.Open()
Dim dr As OleDbDataReader = OleDbCmd.ExecuteReader()
Dim bulkCopy As SqlBulkCopy = New SqlBulkCopy(sSqlConnectionString)
bulkCopy.DestinationTableName = sSQLTable
bulkCopy.WriteToServer(dr)
OleDbConn.Close()
