C#读取Excel文件数据

相当简单,Excel就像数据库,每个Sheet就是一个Table. Microsoft.Jet.OLEDB驱动.
之后是DataReader循环,或DataSet处理都非常简单.

注意:数据类型的转换!!

#region set connection
string strConn = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source= "+this.txtPath.Text+";Extended Properties=Excel 8.0;";
myDataReader = null;
craboDbConnection = new OleDbConnection(strConn);
OleDbCommand myOleDbCommand = new OleDbCommand("SELECT * FROM [Sheet1$]", myOleDbConnection);
#endregion

try
{
myOleDbConnection.Open();
myDataReader = myOleDbCommand.ExecuteReader();
while (myDataReader.Read())
{
this.txtSeq.Text=Convert.ToString(myDataReader.GetValue(0));//列1
this.txtName.Text=Convert.ToString(myDataReader.GetValue(1));//列2
this.txtPIN.Text=Convert.ToString(myDataReader.GetValue(2));//列3
}
}
#region Catch
catch(System.Threading.ThreadAbortException e)
{
System.Threading.Thread.ResetAbort();
this.lblResult.Text = "线程被中断..."+e.Message;
}
catch(Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.ToString());
}
finally
{
// Always call Close when done reading.
if (myDataReader != null)
myDataReader.Close();

// Close the connection when done with it.
if (craboDbConnection!=null && craboDbConnection.State == ConnectionState.Open)
craboDbConnection.Close();

if(webResponse!=null)
webResponse.Close();
}
#endregion
