Checking for datareader returned types at runtime

[Guest]

dr is a dataset, str1 is a string. How can I know the type inside the
datareader field?
I tried:

if(dr.GetValue(n) is System.Int32)
str1=Convert.ToString(dr.GetSqlInt32(n))
else
str1=dr.GetString(n)

But the compiler warns the if is always false.
Thanks in advance

Sorry, dr is a SqlDatareader

I solved the problem with:
if(rsAux.GetFieldType(n).FullName == "System.Int32" )
