Hello C# code experts,
I am building a C# program which requires that I parse a CSV formatted database, store the data into a two dimension array whose elements I could access and do data manipulations on.
The problem is how do I store them and how do I access them without using a standard database software like Access, Oracle or SQL Server to do data manipulations?
Below is my attempt at this. What am I doing wrong? Also I want to produce an output csv file. How would I do it?
{
//Create an Arraylist
System.Collections.ArrayList myArraylist =
new System.Collections.ArrayList();
//Create a new DataSet
DataSet myDataSet =
new DataSet();
//Create a DataTable to contain the data
DataTable GNGTable2 =
new DataTable();
//Creates and Names 6 columns and adds them to GNGTable1
myDataSet.Tables.Add("GNGTable2");
//Declare item property for later access
DataColumn aColumn;
for(int counter=0; counter < 6; counter++)
{
aColumn =
new DataColumn("Column " + counter.ToString());
myDataSet.Tables["GNGTable2"].Columns.Add(aColumn);
}
// Create the StreamReader to read the streamreader class
System.IO.StreamReader myReader =
new System.IO.StreamReader("C:\\GNGFile.csv");
string myString;
//Check to see if the StreamReader has reached the end of the record
string strFirstName;
string strLastName;
string strAddress;
string strCity;
string strState;
string strZip;
string[] fields;
while (myReader.Peek() != -1)
{
//Reads a line of data from the text file
myString = myReader.ReadLine();
//Assign output to myString
fields = myString();
strFirstName = fields[1];
strLastName = fields[2];
strAddress = fields[3];
strCity = fields[4];
strState = fields[5];
strZip = fields[6];
//Use the StringSplit method to create an array of strings as an entry
//that represents each field in a row. The array is then added
//as a new DataRow in GNGTable1
myDataSet.Tables["GNGTable2"].Rows.Add(myString.Split(
char.Parse(",")));
//myArraylist.Add(myDataSet);
}
//myAdapter.GetFillParameters(myDataSet);
dataGrid1.DataSource = myDataSet(strFirstName,strLastName,strAddress,strCity,strState,strZip);
}
Would really appreciate your help,
