C# parse string “0” to integer

Question

I have a new laptop at work and code that worked earlier in the week does not work today.

The code that worked before is, simplified:

while (dr.Read         


        

Answer 1

you should check dr["FieldName"] != DBNull.Value and you should use TryParse if it passes the DBNull test...

if ( dr["FieldName"] != DBNull.Value )
{
    int val = 0;
    if ( int.TryParse( dr["FieldName"], out val ) )
    {
        i = val;
    }
    else
    {
        i = 0; // or some default value
    }
}
