ASP.NET Excel导入到SQL Server数据库
ASP.NET Excel导入到SQL Server数据库
提供把Excel里的数据导入到SQL Server 数据库，前提是Excel里的字段在Sql Server表里都有，不然会出现错误。注释很详细哦！要引用的命名空间是：
using System.Data.OleDb;
using System.Data.SqlClient;
//操作类
public class ExcelToSQL
{
//string SqlConnectionString = "Server=(local);Initial Catalog=Test;Integrated Security=True";
public SqlConnection sqlcon; //创建SQL连接
public SqlCommand sqlcom; //创建SQL命令对象
public ExcelToSQL()
{
DataOperation dataOperation = new DataOperation(); //用到平台的函数，就是初始化SqlConnection对象
DBUnit dbUnit = dataOperation.GetDbUnit();
sqlcon = (SqlConnection)dbUnit.cnt;
if (sqlcon.State.ToString() == "Open")
sqlcon.Close();
}
public int ImportSql(string excelPath, string tableName) //导入的Excel的路径，数据库里的表名
{
if (!TableExist(tableName)) //表名是否存在
return (int)ImportState.tableNameError;
DataTable dt = ExcelToDataTable(excelPath);
if (dt == null)
{
&nbs
