How to Get TaxonomyField value for Current listitem?

Answer 1

You can use code which use following classes to get the Taxonomy Field labels..

TaxonomyFieldValueCollection coll = (list.Items[0]["Field Name"] as TaxonomyFieldValueCollection);

StringBuilder sb = new StringBuilder();

        foreach (TaxonomyFieldValue val in coll)
        {
            // get termguid
            string termGuid = val.TermGuid;

            // get label
            string label = val.Label;

            // build the string
            sb.AppendLine(string.Format("GUID: {0}, Label: {1}", termGuid, label));
        }

        lblFieldViewer.Text = sb.ToString();

Answer 2

I found the value by below way:

        TaxonomyField fieldToSet = ListItem.Fields["TexonomyType"] as TaxonomyField;
        string value = string.Empty;
        if (fieldToSet != null)
        {
            object itemObj = ListItem["TexonomyType"];
            value = Convert.ToString(fieldToSet.GetFieldValueAsText(itemObj));
        }

Hops its helps.
