How to compare to System.Type ?

Question

Hi guys.

In DataSet.Tables[0].Columns[0] we have a DataType property. Now, I would like to iterate over Columns and perform some action depending on the Type in DataType. How to do this?

foreach(var c in DataSet.Tables[0].Columns)
{
  if (c.DataType == System.String) {} //error 'string' is a 'type', which is not valid in the given context

}

Answer 1

Use the typeof operator:

if (c.DataType == typeof(string))
{
    // ...
}

Answer 2

Try this...

if (c.DataType == typeof(string)) {}

Answer 3

if (c.DataType == typeof(string))
{
    // code
}
