Question

I have a dataset of values, which I need to put into a textbox. However, there are some decimal and double type values in my dataset, so I need to cast them toString(). Furthermore, sometimes the dataset values are empty, so before casting toString() I need to check whether there is actually a value there or not.
This is sample line:

I need code that does something like this…

if(ds.Tables[0].Rows[0].Field<decimal>("IndexPrethodni") !=null or something){
    Convert.ToString(ds.Tables[0].Rows[0].Field<decimal>("IndexPrethodni"));
}

I known decimal is not a nullable type. Is there any easy solution to achieve my desired result?

Answer 1

check for DBNull

if(ds.Tables[0].Rows[0].Field(“IndexPrethodni”) != DBNull.Value) {
//convert to string
}
