Writing a method that will accept table as an input

I want to write a method that can accept a table as input, i.e.:

void Take_something_from_table(string table_name)
{
  DataClassesDataContext 开发者_开发问答dc = new DataClassesDataContext();              
  var queryResult = from a in dc.GetTable<*table_name*>()  //without * of course 
                    select a;

  ...
}

I want a method that will be called Take_something_from_table(Test_table)

I tried this and got this error:

The type or namespace name 'table_name' could not be found (are you missing a using directive or an assembly reference?)

HELP!!

i agree with leppie, or if u wana keep that string as table name then define and enum or else and place If Else block to perform action. for example

if(TabmeNameA)
{
   // Execute Query for table A
}
if(TabmeNameB)
{
   // Execute Query for table B
}
