How to set the GDAL_DATA environment variable to point to the directory containing EPSG csv files?

Question

I want to wrap(re-project) one variable in this netcdf file.

D:\\ gdalwarp -t_srs EPSG:4326 NETCDF:"C:\\fie.nc":var "C:\\Desktop\\SM.img"

You can also use for making programmatically(with C# API). Sample code:

string path = @"C:\abc\";
_SetValueNewVariable("GDAL_DATA", path + "\\data");
_SetValueNewVariable("GEOTIFF_CSV", path + "\\data");
_SetValueNewVariable("GDAL_DRIVER_PATH", path + "\\gdalplugins");

private static void _SetValueNewVariable(string sVar, string sValue)
{
    if (System.Environment.GetEnvironmentVariable(sVar) == null)
       System.Environment.SetEnvironmentVariable(sVar, sValue);
}
