Hi developers!
I'm Vishal Sharma.
My problem is I have a csv file that can contain 1 MB data and csv file loads in the dataset and shows in DataGridView, data contains a Regular Expression in multiple columnns or rows; I do not know which columns contain regular expressions, so I want replace mehod work on all the columns or rows in the dataset.
I have a code that contains System.Text.Regex for replace each rows but I do not know how all the rows taken in a parameter.

The code is:

C#

string str = ",";
string mtr = "/";
foreach (DataRow datarow in dataset.Tables[0].Rows)
    {
        datarow[]= regex.replace(str.tostring, mtr.tostring)
    }

The datarow index I want to take all the rows, not a single row and I do not how more rows in my dataset.

~~please solve this code imediatly~~
Why? Are you my boss?

Mr Vishal try like this,

C#

string str = ",";
string mtr = "/";
foreach (DataRow datarow in dataset.Tables[0].Rows)
 {
   foreach(DataColumn datacol in dataset.Tables[0].Columns)
   {
     datarow[datacol]= regex.Replace(datarow[datacol].ToString(), str.tostring, mtr.tostring);
   }
}
