Question

I have the following class:

public class VendorClass {         
    public int VendorID { get; set; }
    public string VendorName { get; set; }
}

The fields above match fields in the database table.
In the case of say VendorName, how do I give it a field width ?

VendorName maps to a field in the database which is varchar(15)

You can’t limit the length of the string but you can use properties with backing fields to achieve the desired result :

public class VendorClass
{
    public int VendorID {  get; set; }

    private string _vendorName;

    public string VendorName
    {
        get { return _vendorName; }
        set
        {
            if (value.Length > 15)
            {
                _vendorName = value.Substring(0,15);                    
            } else { 
                _vendorName = value;
            }
        }
    }
}
