asp.net中word导入数据库问题

将Excel文件数据库导入SQL Server的三种方案//方案一： 通过OleDB方式获取Excel文件的数据，然后通过DataSet中转到SQL ServeropenFileDialog = new OpenFileDialog();
openFileDialog.Filter = "Excel files(*.xls)|*.xls";if(openFileDialog.ShowDialog()==DialogResult.OK)
{
FileInfo fileInfo = new FileInfo(openFileDialog.FileName);
string filePath = fileInfo.FullName;
string connExcel = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filePath + ";Extended Properties=Excel 8.0";

try
{
OleDbConnection oleDbConnection = new OleDbConnection(connExcel);
oleDbConnection.Open();

//获取excel表
DataTable dataTable = oleDbConnection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null); //获取sheet名，其中[0][1]...[N]: 按名称排列的表单元素
string tableName = dataTable.Rows[0][2].ToString().Trim();
tableName = "[" + tableName.Replace("'","") + "]"; //利用SQL语句从Excel文件里获取数据
//string query = "SELECT classDate,classPlace,classTeacher,classTitle,classID FROM " + tableName;
string query = "SELECT 日期,开课城市,讲师,课程名称,持续时间 FROM " + tableName;
dataSet = new DataSet(); //OleDbCommand oleCommand = new OleDbCommand(query, oleDbConnection);
//OleDbDataAdapter oleAdapter = new OleDbDataAdapter(oleCommand);
OleDbDataAdapter oleAdapter = new OleDbDataAdapter(query,connExcel);

oleAdapter.Fill(dataSet,"gch_Class_Info"); //dataGrid1.DataSource = dataSet;
//dataGrid1.DataMember = tableName;
dataGrid1.SetDataBinding(dataSet,"gch_Class_Info"); //从excel文件获得数据后，插入记录到SQL Server的数据表
DataTable dataTable1 = new DataTable();

SqlDataAdapter sqlDA1 = new SqlDataAdapter(@"SELECT classID, classDate,
classPlace, classTeacher, classTitle, durativeDate FROM gch_Class_Info",sqlConnection1);

SqlCommandBuilder sqlCB1 = new SqlCommandBuilder(sqlDA1);

sqlDA1.Fill(dataTable1); foreach(DataRow dataRow in dataSet.Tables["gch_Class_Info"].Rows)
{
DataRow dataRow1 = dataTable1.NewRow();

dataRow1["classDate"] = dataRow["日期"];
dataRow1["classPlace"] = dataRow["开课城市"];
dataRow1["classTeacher"] = dataRow["讲师"];
dataRow1["classTitle"] = dataRow["课程名称"];
dataRow1["durativeDate"] = dataRow["持续时间"]; dataTable1.Rows.Add(dataRow1);
} Console.WriteLine("新插入 " + dataTable1.Rows.Count.ToString() + " 条记录");
sqlDA1.Update(dataTable1);

oleDbConnection.Close(); }
catch(Exception ex)
{
Console.WriteLine(ex.ToString());
}
}//方案二： 直接通过SQL语句执行SQL Server的功能函数将Excel文件转换到SQL Server数据库OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.Filter = "Excel files(*.xls)|*.xls";SqlConnection sqlConnection1 = null;if(openFileDialog.ShowDialog()==DialogResult.OK)
{
string filePath = openFileDialog.FileName; sqlConnection1 = new SqlConnection();
sqlConnection1.ConnectionString = "server=(local);integrated security=SSPI;initial catalog=Library"; //import excel into SQL Server 2000
/*string importSQL = "SELECT * into live41 FROM OpenDataSource" +
"('Microsoft.Jet.OLEDB.4.0','Data Source=" + "\"" + "E:\\022n.xls" + "\"" +
"; User ID=;Password=; Extended properties=Excel 5.0')...[Sheet1$]";*/ //export SQL Server 2000 into excel
string exportSQL = @"EXEC master..xp_cmdshell
'bcp Library.dbo.live41 out " + filePath + "-c -q -S" + "\"" + "\"" +
" -U" + "\"" + "\"" + " -P" + "\"" + "\"" + "\'";

try
{
sqlConnection1.Open();

//SqlCommand sqlCommand1 = new SqlCommand();
//sqlCommand1.Connection = sqlConnection1;
//sqlCommand1.CommandText = importSQL;
//sqlCommand1.ExecuteNonQuery();
//MessageBox.Show("import finish!");

SqlCommand sqlCommand2 = new SqlCommand();
sqlCommand2.Connection = sqlConnection1;
sqlCommand2.CommandText = exportSQL;
sqlCommand2.ExecuteNonQuery();
MessageBox.Show("export finish!");
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}
}if(sqlConnection1!=null)
{
sqlConnection1.Close();
sqlConnection1 = null;
}
//方案三： 通过到入Excel的VBA dll，通过VBA接口获取Excel数据到DataSetOpenFileDialog openFile = new OpenFileDialog();
openFile.Filter = "Excel files(*.xls)|*.xls";ExcelIO excelio = new ExcelIO();if(openFile.ShowDialog()==DialogResult.OK)
{
if(excelio!=null)
excelio.Close(); excelio = new ExcelIO(openFile.FileName);
object[,] range = excelio.GetRange();
excelio.Close();
DataSet ds = new DataSet("xlsRange"); int x = range.GetLength(0);
int y = range.GetLength(1); DataTable dt = new DataTable("xlsTable");
DataRow dr;
DataColumn dc;

ds.Tables.Add(dt); for(int c=1; c<=y; c++)
{
dc = new DataColumn();
dt.Columns.Add(dc);
}

object[] temp = new object[y];

for(int i=1; i<=x; i++)
{
dr = dt.NewRow(); for(int j=1; j<=y; j++)
{
temp[j-1] = range[i,j];
}

dr.ItemArray = temp;
ds.Tables[0].Rows.Add(dr);
} dataGrid1.SetDataBinding(ds,"xlsTable");

if(excelio!=null)
excelio.Close();
}
