The only way I found to change the HtmlEncode property on a bound column when auto-generating the grid-view.

protected void grFeedHistoryView_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            BoundField field = (BoundField)((DataControlFieldCell)e.Row.Cells[2]).ContainingField;
            field.HtmlEncode = false;
        }

Don’t recall where I found this but converts List to DataTable.

public static System.Data.DataTable ToDataTable<T>(this IList<T> data)
        {
            System.ComponentModel.PropertyDescriptorCollection props = System.ComponentModel.TypeDescriptor.GetProperties(typeof(T));
            System.Data.DataTable table = new System.Data.DataTable();
            for (int i = 0; i < props.Count; i++)
            {
                System.ComponentModel.PropertyDescriptor prop = props[i];
                table.Columns.Add(prop.Name);
                //table.Columns.Add(prop.Name, prop.PropertyType);
            }
            object[] values = new object[props.Count];
            foreach (T item in data)
            {
                for (int i = 0; i < values.Length; i++)
                {
                    values[i] = props[i].GetValue(item);
                }
                table.Rows.Add(values);
            }
            return table;
        }

Pieced this together from stackoverflow… http://stackoverflow.com/questions/2912476/using-c-sharp-to-check-if-string-contains-a-string-in-string-array/2912541#2912541

string stringToCheck = "text1";
string[] stringArray = { "text1", "testtest", "test1test2", "test2text1" };

This checks if stringToCheck contains any one of substrings from stringArray.

if(stringArray.Any(stringToCheck.Contains))

If you want to ensure that it contains all the substrings, change Any to All:

if(stringArray.All(s => stringToCheck.Contains(s)))
