Well, what blocks you from doing it? By the way, use generic collection instead of obsolete HashTable.
I think you already got all the answers you need.

OK let me try t give you a solution, bit lengthy but it could work. [NOTE: all pseudocode, only logic no syntactic accuracy]

have a class/struct to hold the tab separated data and a function inside to do the split

C#

class columcollecton
{
string0;
string1;
string2;

public void SplitAndPopulate(string line)
{
   string[] str = line.split('\t');
   string0 = str[0];
   string1 = str[1];
   ...
   ...
}

}

now in you original code

C#

private void btnReadFile_Click(object sender, EventArgs e)
{
   string[] lines = File.ReadAllLines(txtFilePath.Text); //
   Hashtable ht = new Hashtable();
   foreach(string line in lines)
   {
     //create columncollection object
     //call the SplitAndPopulate
     //add the custom struct you have in hastable, internally the struct contains tab separated strings
     //NOTE: I think it would be better if you use a Dictionary instead of hashtable.
   }  
}

Solution 1

I suspect you are using static methods provided by the File class to read the files. I would suggest using Stream as that is better if used wisely.

For your question, there is a method called Split in the String class. Look it up.

You can split each line of array on tab character using

String.Split()

method.
After splitting, it'll create create another string array containing column information.
After that you can either use this new array or add all elements of this array to a Hashtable and use it.

Please let me know if you need something else.

enter array variable in hash table
