1. 新建BaseFunction.cs文件,如下:
using System;
using System.Data;
using System.Data.OleDb;
public class BaseFunction
{
/// <summary>
/// 取得上传文件的数据集
/// </summary>
/// <param name="strUpFileExtName">上传文件扩展名</param>
/// <param name="strUpFileName">上传文件名</param>
/// <param name="strUpPath">上传的路径</param>
/// <param name="strSplitChar">拆分字符或Excel表名</param>
/// <param name="aryField">要导入的数据字段数组</param>
/// <returns></returns>
public static DataSet GetOleDbData(string strUpFileExtName, string strUpFileName, string strUpPath, string strSplitChar, string[] aryField, bool preview)
{
string strDBDatabaseName;
string DBSQL;
if (preview)
{
DBSQL = "select top 10 * from {0}";
}
else
{
DBSQL = "select * from {0}";
}
string oleConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties={1}";
switch (strUpFileExtName)
{
case ".xls":
{
strDBDatabaseName = strUpPath + strUpFileName;//excel数据库完整文件名作为数据源
DBSQL = String.Format(DBSQL, "[" + strSplitChar + "$]");//"SELECT * FROM ["+tbExcel.Text+"＄]"; //硬性规定只能在Sheet1工作表中存放数据
oleConnStr = String.Format(oleConnStr, strDBDatabaseName, "Excel 8.0");
break;
}
}
//通过ole数据提供者获得数据
OleDbConnection oleConnection = new OleDbConnection(oleConnStr);
OleDbDataAdapter dbdat = new OleDbDataAdapter(DBSQL, oleConnection);
DataSet upDs = new DataSet();
try
{
dbdat.Fill(upDs, "UpTable");
if (upDs.Tables["UpTable"].Columns.Count > aryField.Length)
{
//上传的字段不合法
throw new Exception("上传的文件字段不符合规则!列数为" + upDs.Tables["UpTable"].Columns.Count.ToString());
}
}
catch (Exception ex)
{
throw new Exception("查询上传数据时出错！" + ex.Message);
}
finally
{
if (dbdat != null)
{
dbdat.Dispose();
dbdat = null;
}
if (oleConnection != null)
{
oleConnection.Dispose();
oleConnection = null;
}
}
return upDs;
}
}
