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.

Try Type.GetType("System.Boolean") instead of typeof(bool).
 
Hi Hunter,

Error states that I cannot use "==" operator period when comparing Boolean.

I have tried what you suggested and it does not work.

Strange. Works for me with .Net 1.1
 
This works, .NET - FW2.0

DataColumn myColumn = new
DataColumn("name",System.Type.GetType("System.Boolean"));

if (myColumn.DataType == typeof(bool))

{

if (myColumn.DataType == typeof(Boolean))

{

xxx = "okay";

}

}
 
Hi Miha,

Thanks for replying.

myColumn is just an iterator for a row.

foreach (DataColumn myColumn from myTable.Columns)

Thanks.

Hi Jay,

That code should work.
What is the myColumn type exactly?

Can you create a simple sample that reproduces the problem?

Jay,

Can you show the code as you did that,
This should in my opinion be the same in 1.x as in 2.0
