Set a row value to Null

[BerndtNording]

How does one set a row value to null?

pRow.Value(i) = "" sets it to an empty string
pRow.Value(i) = nothing also sets it to an empty string
pRow.Value(i) = system.dbnull  generates an error

in the field calculator you can create an expression like Field1 = null and it will set the values to Null, but how do you do it in .NET?

Check out this link.  It seems to list a way to generate a null value, at least for date fields.  Let me know if this points you in the right direction.

See also this link for string fields.  It seems you should use

field.value = dbNull.value.

Try:

pRow.Value(i) = System.DBNull.Value
