After your edit where we see you have an enum, the solution is:

if (FieldTypeInfo == FieldType.TextBox)
{ 
  ...
}

if (FieldTypeInfo == FieldType.DropDownList)
{
  ...
}

However, strongly consider using a switch statement, for example:

switch (FieldTypeInfo)
{
  case FieldType.TextBox:
    ...
    break;

  case FieldType.DropDownList:
    ...
    break;

  default:
    ...
    break;
}

Use Object.GetType 

if(FieldTypeInfo.GetType()== typeOf(TextBox))
{
}

Or is

if (FieldTypeInfo is DropDownList)
{
}

You can use the is keyword in order to check types:

if (FieldTypeInfo is TextBox)
{
    var text = ((TextBox)FieldTypeInfo).Text;
    // ...
} 
else if (FieldTypeInfo is DropDownList)
{
    // ...
}
