How to pass credentials to a SOAP webservice?

Question

I am trying to call a SOAP webservice, however I am getting the error: Additional information: The username is not provided. Specify username in ClientCredentials.

So I thought I could just set client.ClientCredentials to a new instance of NetworkCredentials. However ClientCredentials is read only. So how can I go about passing this information on to access the web service?

    myService.ServiceClient client = new myService.ServiceClient();
    // This won't work since its read only.                
    client.ClientCredentials = new System.Net.NetworkCredential("username", "password", "domain");
    string version = client.getData();

EDIT: Binding:

  <binding name="VersionHttpBinding">
    <security mode="TransportCredentialOnly">
      <transport clientCredentialType="Basic" />
    </security>
  </binding>

You'll need to set the credentials on the client, like as shown in this MSDN article :

client.ClientCredentials.UserName.UserName = "my_user_name";
client.ClientCredentials.UserName.Password = "my_password";
