add field to an IFeatureClass

HectorSanchez_Molinero

Hello, I am beginning to programs with vb.net and c# and of arcobjects do not belong almost anything.

Can someone say to me how add a field (text or integer) to an object of type IFeatureClass and as put then information in him??

I try it this way:

' Create a new fields collection.
            Dim fields As IFields = New FieldsClass()

            ' Cast to IFieldsEdit to modify the properties of the fields collection.
            Dim fieldsEdit As IFieldsEdit = CType(fields, IFieldsEdit)

            ' Set the number of fields the collection will contain.
            fieldsEdit.FieldCount_2 = 1

            ' Create the text field.
            Dim textField As IField = New FieldClass()
            Dim textFieldEdit As IFieldEdit = CType(textField, IFieldEdit)
            textFieldEdit.Length_2 = 30 ' Only string fields require that you set the length.
            textFieldEdit.Name_2 = "Edificio_Afectado"
            textFieldEdit.Type_2 = esriFieldType.esriFieldTypeString

            ' Add the new field to the fields collection.
            fieldsEdit.Field_2(0) = textField


' Here it gives mistake

' Add the field.
            featureClass2.AddField(fields)



Thank you very much. Bye.

' Here it gives mistake

' Add the field.
            featureClass2.AddField(fields)

I have arranged it this way:

' Add the field.
            featureClass2.AddField(fieldsEdit.Field(0)) 


But on having tried to put a Alias does not it take it,

textFieldEdit.AliasName_2 = "Edificio_Afectado"

why it can be?
