Check to see DataColumn DataType is Boolean?Hello,
Iam trying to do the following- if(myColumn.DataType==typeof(bool)) { } I get the error "Operator == cannot be applied to operands type and object and bool." Is there a workaround? Thanks. jay Jay Balapa wrote:

Error states that I cannot use "==" operator period when comparing Boolean. I have tried what you suggested and it does not work. jay Show quote "Sericinus hunter" <serh***@flash.net> wrote in message news:TQ86g.779$zR3.413@newssvr33.news.prodigy.com... > Jay Balapa wrote: >> Hello, >> >> Iam trying to do the following- >> >> if(myColumn.DataType==typeof(bool)) >> { >> } >> >> I get the error "Operator == cannot be applied to operands type and >> object and bool." >> >> Is there a workaround? > > Try Type.GetType("System.Boolean") instead of typeof(bool).

Can you show the code as you did that, This should in my opinion be the same in 1.x as in 2.0 Cor Show quote "Jay Balapa" <jbal***@hotmail.com> schreef in bericht news:uOpWKpvbGHA.3908@TK2MSFTNGP02.phx.gbl... > Iam using 2.0. > > > "Sericinus hunter" <serh***@flash.net> wrote in message > news:7c96g.782$zR3.530@newssvr33.news.prodigy.com... >> Jay Balapa wrote: >>> Hi Hunter, >>> >>> Error states that I cannot use "==" operator period when comparing >>> Boolean. >>> >>> I have tried what you suggested and it does not work. >>> >>> jay >> >> Strange.

That code should work. What is the myColumn type exactly? -- Show quoteMiha Markic [MVP C#] RightHand .NET consulting & development www.rthand.com Blog: http://cs.rthand.com/blogs/blog_with_righthand/ "Jay Balapa" <jbal***@hotmail.com> wrote in message news:OdPENEvbGHA.1208@TK2MSFTNGP02.phx.gbl... > Hello, > > Iam trying to do the following- > > if(myColumn.DataType==typeof(bool)) > { > } > > I get the error "Operator == cannot be applied to operands type and object > and bool." > > Is there a workaround? > > Thanks. > jay > > > > Hi Miha,
Thanks for replying. myColumn is just an iterator for a row. foreach (DataColumn myColumn from myTable.Columns) Thanks. jay Show quote "Miha Markic [MVP C#]" <miha at rthand com> wrote in message news:ugSGME1bGHA.4108@TK2MSFTNGP03.phx.gbl... > Hi Jay, > > That code should work. > What is the myColumn type exactly? > > -- > Miha Markic [MVP C#] > RightHand .NET consulting & development www.rthand.com > Blog: http://cs.rthand.com/blogs/blog_with_righthand/ > > "Jay Balapa" <jbal***@hotmail.com> wrote in message > news:OdPENEvbGHA.1208@TK2MSFTNGP02.phx.gbl... >> Hello, >> >> Iam trying to do the following- >> >> if(myColumn.DataType==typeof(bool)) >> { >> } >> >> I get the error "Operator == cannot be applied to operands type and >> object and bool." >> >> Is there a workaround? >> >> Thanks. >> jay >> >> >> >> > > Can you create a simple sample that reproduces the problem?
