用C#如何将Excel导入到SQL Server

作者：被偷De贼

Excel的导入一定给客户规定统一的模板,这样才能方便做业务处理.

我是这样做的.

首先将Excel的所有Sheet页全都读出来,请用户选择要处理的Sheet的页,获取Sheet页代码如下

Code
/      //
        /// 获取Excel的表名[Sheet1$]
        ///
        /// Excel的路径
        /// DataTable
        public static DataTable GetExcelTableName(string path)
        {
       
            var conn = GetConnection(path);
            var dt = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
           
           
            conn.Close();
            return dt;
        }

返回的DataTable可以绑定到Listbox控件中,
当用户选择好要处理Sheet页后,将选择的Sheet页名称输入到下面的方法,以获取所选Sheet页的内容:

 

Code
        /// 
/// 根据Excel的表名,获取相应表的内容
/// 
/// Excel的表名
/// Excel路径
/// 
        public static DataTable GetExcelTable(string tableName,string path)
        {

            var sql = string.Format("SELECT * FROM [{0}]", tableName);
            var conn = GetConnection(path);
            var myCommand = new OleDbDataAdapter(sql, conn); 
            var myDataSet = new DataSet(); 
            myCommand.Fill(myDataSet); 
return myDataSet.Tables[0];
        }

 

返回一个DataTable,这样你就可以根据自己的业务来处理DataTable中的数据了.
完整的代码如下:

 

Code
using System.Data;
using System.Data.OleDb;
using System.Windows.Forms;

        }
static OleDbConnection GetConnection(string path)
        {
            var strConn=string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=Excel 8.0;",path);
            var conn = new  OleDbConnection(strConn);
            conn.Open();
return conn;

        }
/// 
/// 获取Excel的表名[Sheet1$]
/// 
/// Excel的路径
/// DataTable
        public static DataTable GetExcelTableName(string path)
        {

            var conn = GetConnection(path);
            var dt = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);


            conn.Close();
return dt;
        }
/// 
/// 获取Excel的路径
/// 
/// 路径
        public static string GetExcelPath()
        {
            var dlg = new OpenFileDialog {Filter = "Microsoft Excel|*.xls"};
return dlg.ShowDialog() == DialogResult.OK ? dlg.FileName : string.Empty;
        }
/// 
/// 根据Excel的表名,获取相应表的内容
/// 
/// Excel的表名
/// Excel路径
/// 
        public static DataTable GetExcelTable(string tableName,string path)
        {

            var sql = string.Format("SELECT * FROM [{0}]", tableName);
            var conn = GetConnection(path);
            var myCommand = new OleDbDataAdapter(sql, conn); 
            var myDataSet = new DataSet(); 
            myCommand.Fill(myDataSet); 
return myDataSet.Tables[0];
        }
    }
}
