Sample code that demonstrates how to open an existing shapefile and save that shapefile with a new file name.
using DotSpatial.Data; privatevoid button1_Click(object sender, EventArgs e) { //Declare a new feature set IFeatureSet fs = FeatureSet.Open(@"C:\[Your File Path]\Municipalities.shp"); //Saves the open shapefile fs.SaveAs(@"C:\[Your File Path]\Municipalities_Test.shp", true); }
