Adding Field using C# winform and ArcObjects?

Question

How to add a field in featureclass by using C# winform,arcobjects?

It means when we click on command winform should open and afetr field entries it should be add in to table.

• Michael Stimson: Can you please post some code to show where you're stuck. You can use Windows Forms to access ArcObjects, either as an add-in or a standalone program (I would need to know which one it is) also, is it a local dataset or do you intend to do this over a web interface?

Answer 1

The following function will add a field to a feature class:

private void AddField(IFeatureClass fClass, string name, string alias, esriFieldType dataType)
{
 IField newField = new FieldClass();
 IFieldEdit fieldEdit = (IFieldEdit)newField;
 fieldEdit.Name_2 = name;
 fieldEdit.AliasName_2 = alias;
 fieldEdit.Type_2 = dataType;
 fClass.AddField(newField);
}

There are, of course, more properties that can be set on the field, this is just a sample of how to set them - the properties ending '_2' on IFieldEdit are the writable ones.
