How to reference SQL columns containing quotes?

I am having trouble referencing the "current" column. It was originally named using quotes, and I am not sure how to reference it.
I have tried:

 colName = "\"current\"";
 colName = "\'current\'";
 colName = "current";

 Using the query:
 query = "SELECT" + colName "FROM myTable";
 cmd = new SQLCommand(query,Conn);
 cmd.CommandText = query;
 adpt = new SQLDataAdapter(query,Conn);
 table = new DataTable();
 adpt.Fill(table);

All to no avail. It keeps saying the column does not belong to the table, I can easily reference any other column successfully.

 CREATE TABLE dbo.myTable
(
   id              int identity    NOT NULL,
   puffid          int,
   summaryid       int,
   serial_number   int,
   puff_date_time  datetime,
   x_angle         numeric(8,3)    DEFAULT ((0)),
   y_angle         numeric(8,3)    DEFAULT ((0)),
   z_angle         numeric(8,3)    DEFAULT ((0)),
   voltage         numeric(8,3)    DEFAULT ((0)),
   "current"       numeric(8,3)    DEFAULT ((0)));
   GRANT DELETE, REFERENCES, UPDATE, SELECT, INSERT ON dbo.myTable TO dbo;

I really have no idea how to reference this thing. I can't change the column name or it will break multiple other parts of the project.

You will need to wrap them into [ and ] and you need spaces around them as well:

 colName = "\"current\"";

 Using the query:
 query = "SELECT [" + colName + "] FROM myTable";
 cmd = new SQLCommand(query,Conn);
 cmd.CommandText = query;
 adpt = new SQLDataAdapter(query,Conn);
 table = new DataTable();
 adpt.Fill(table);

Honestly, if you can, I suggest you rename the column to current. This can be done with sp_rename:

EXEC sys.sp_rename N'dbo.myTable.["current"]',N'current','COLUMN';

If you can't, then you'll need to escape the double quotes that are part of the name or use T-SQL's delimit identifier too. Either """current""" or ["current"] would work to reference the column.
