Checking if a string is in date format

[feurich]

Hi there,

 

I am trying to check if a date string 12-12-2005 is in date format in C#. But I can't seem to find a way of doing it.

I just get a string like 12-12-2005 and I want to check if this string is in the regional date format.

 

Thanks,

[csharp]

private void button1_Click(object sender, System.EventArgs e)

{

if (CheckIfDate(textBox1.Text))

{

MessageBox.Show("Deze string voldoet aan het datum formaat");

}

else

{

MessageBox.Show("Deze string voldoet niet aan het datum formaat");

}

}

 

private bool CheckIfDate(string Value)

{

try

{

System.DateTime odate = (DateTime)(TypeDescriptor.GetConverter(new DateTime(1990,5,6)).ConvertFrom(textBox1.Text));

textBox2.Text = odate.Date.ToString();

return true;

}

catch

{

return false;

 

}

You could also use DateTime.Parse() or DateTime.ParseExact() to try the conversion rather than relying on a TypeDescriptor.GetConverter.

Hi PD,

 

Looked at your suggestion and it makes sense. Less code and more clear.

 

Thanks,
