Hi,<br><br>I think you'd better to use the OGR C# API (ogr_csharp.dll) to get all the features of the layer, see the ogrinfo example for the details:<br><a href="http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/ogrinfo.cs">http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/ogrinfo.cs</a><br>

<p>Hi</p>
<p> </p>
<p>What is the best way to retrieve all records of a layer. Some
options I see is</p>
<p> </p>
<p style="text-indent: -0.25in;"><span>1.<span style="font-family: "Times New Roman"; font-style: normal; font-variant: normal; font-weight: normal; font-size: 7pt; line-height: normal; font-size-adjust: none; font-stretch: normal;">
</span></span><span dir="ltr"></span>calling
queryByRect(mapObj.extents) – But this will not get all records if map
extents are smaller than layer extents</p>
<p style="text-indent: -0.25in;"><span>2.<span style="font-family: "Times New Roman"; font-style: normal; font-variant: normal; font-weight: normal; font-size: 7pt; line-height: normal; font-size-adjust: none; font-stretch: normal;">
</span></span><span dir="ltr"></span>layer.whichShapes() – But this
will apply filter set on the layer. I want to get all records. </p>
<p style="text-indent: -0.25in;"><span>3.<span style="font-family: "Times New Roman"; font-style: normal; font-variant: normal; font-weight: normal; font-size: 7pt; line-height: normal; font-size-adjust: none; font-stretch: normal;">
</span></span><span dir="ltr"></span>call queryByAttribute() and pass
some expression that will select everything </p>
<p> </p>
<p>Or, is there any more straight forward API to get all
records.</p>
<p> </p>
<p>Thanks</p>
<p>Murty</p>
