Contoh

Contoh kode berikut menunjukkan penggunaan WsdlContractConversionContext untuk menambahkan anotasi WSDL kustom ke metadata yang diekspor menggunakan WsdlPortType properti dan Contract . Saat mengekspor operasi, metode berulang melalui deskripsi operasi, dan menemukan masing-masing yang terkait System.Web.Services.Description.Operation dengan memanggil GetOperation metode .

Console.WriteLine("Inside ExportContract");
if (context.Contract != null)
{
    // Inside this block it is the contract-level comment attribute.
    // This.Text returns the string for the contract attribute.
    // Set the doc element; if this isn't done first, there is no XmlElement in the
    // DocumentElement property.
    context.WsdlPortType.Documentation = string.Empty;
    // Contract comments.
    XmlDocument owner = context.WsdlPortType.DocumentationElement.OwnerDocument;
    XmlElement summaryElement = Formatter.CreateSummaryElement(owner, this.Text);
    context.WsdlPortType.DocumentationElement.AppendChild(summaryElement);

    foreach (OperationDescription op in context.Contract.Operations)
    {
        Operation operation = context.GetOperation(op);

            // Set the doc element; if this isn't done first, there is no XmlElement in the
            // DocumentElement property.
