}示例2: delteField
public void delteField(IFeatureClass featureClass, string fldNm)
{
ISchemaLock schemaLock = (ISchemaLock)featureClass;
try
{
// A try block is necessary, as an exclusive lock might not be available.
schemaLock.ChangeSchemaLock(esriSchemaLock.esriExclusiveSchemaLock);
int fldIndex = featureClass.FindField(fldNm);
featureClass.DeleteField(featureClass.Fields.get_Field(fldIndex));
}
catch (Exception exc)
{
// Handle appropriately for your application.
Console.WriteLine(exc.Message);
//MessageBox.Show(exc.Message);
}
finally
{
// Set the lock to shared, whether or not an error occurred.
