读取Excel到SQL数据库（方法二）

public void putExcelIntoSQL(string strPath,string strSheetName)
{
try
{
string strConn=System.Configuration.ConfigurationSettings.AppSettings["strCon"];
strConn="Provider=SQLOLEDB;User ID=sa;Initial Catalog=myDatabase;password=;datasource=localhost";
OleDbConnection Olecon=new OleDbConnection(strConn);
string sql="";
sql="insert INTO tableTest ";
sql = sql + " select JAN";
sql = sql + ",商品名";
sql = sql + ",部門,状態";
sql = sql + ",棚卸単位";
sql = sql + ",棚卸単位入数";
sql = sql + ",棚卸原単";
sql = sql + ",棚卸売単 ";
sql = sql + "FROM OpenDataSource('Microsoft.Jet.OLEDB.4.0','Data Source=/"";
sql = sql + strPath + "/"" ;
sql = sql + ";User ID=Admin;Password=;Extended properties=Excel 5.0')...["+ strSheetName +"$]";
OleDbCommand oleCmd=new OleDbCommand(sql,Olecon);
Olecon.Open();
oleCmd.ExecuteNonQuery();
Olecon.Close();
}
catch(Exception ex)
{
throw ex;
}
}

注意：Excel中若有混合类型的数据，则有可能出现读取数据丢失现象，
可以通过修改注册表来解决：
在HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Jet/4.0/Engines/Excel中修改TypeGuessRows的值，最好修改为0。
