Question

I just want to insert some data from a datatable to a list.

Here is my class:

class WhereColumnValue
{
    private string columnName;

    public string _columnName
    {
        get { return columnName; }
        set { columnName = value; }
    }

    private string setValue;

    public string _setValue
    {
        get { return setValue; }
        set { setValue = value; }
    }

    private bool setValueStatus;

    public bool _setValueStatus
    {
        get { return setValueStatus; }
        set { setValueStatus = value; }
    }
}

Now i have a list of WhereColumnValue type.

List<WhereColumnValue> lstWhereColumnValue = new List<WhereColumnValue>();

How could I insert data to this lstWhereColumnValue?

I have tried following code:

foreach (DataRow tmp in dtAllColumnData.Rows)
            {
                lstColumn.Add(tmp["COLUMN_NAME"].ToString());
                lbTableColumns.Items.Add(tmp["COLUMN_NAME"]);
                lstWhereColumnValue.Add(***);

            }

I have to add an item here(*). but i only have value for _columnValue. Rest two will remain null. how would i do this?

Answer 1

You need to instantiate your class and add filled-out instances of it to your list. Something like this:

foreach (DataRow tmp in dtAllColumnData.Rows)
{
    WhereColumnValue val = new WhereColumnValue();
    val._columnName = tmp["COLUMN_NAME"];
    val._setValue = tmp{"SET_VALUE"];
    ....
    lstColumn.Add(val);
}

You may also want to follow naming conventions and have your properties be ColumnName, SetValue, etc.
