Question

My goal is to trim all string datatypes within my dataset and then replace the “untrimmed” with the trimmed.

I encounter the following error:
“ArgumentException was unhandled – String was not recognized as a valid DateTime.Couldn’t store <> in DateofBirth Column. Expected type is DateTime.”

when I run the following code:

foreach (DataRow y in ds.Tables[0].Rows)
{
    for (int i = 0; i < ds.Tables[0].Columns.Count -1; i++)
    {
        if (y[i].GetType() != typeof(DateTime))
        {
            string strTrim = y[i].ToString().Trim();
            y[i] = strTrim;
        }
    }
}

I’m sure I’m on the right track, I just can’t manage to crack it :/

Any help will be appreciated!

Answer 1

If you’re just looking for strings why are you checking for DateTime? Try:

if (y[i] is string)
{
    y[i] = ((string)y[i]).Trim();
}
