Hi, Do you need to validate a row or column? You can convert to int as below- Convert.ToInt32(dt.Rows[0]["colname"].ToString())>0

The first row of the DataTable dt , iterates over its columns and checks if the value in any column is less than or equal to zero. If such a value is found, it throws an exception with an appropriate error message.

You can validate a row in a DataTable by iterating over the columns of the row and checking if any column's value is less than or equal to zero. // Assuming dt is the DataTable containing the row to be validated DataRow row = dt.Rows[0]; // Get the first row foreach (DataColumn col in dt.Columns) { if (row[col] is int value && value
