Here is a quick sample code how to send a value from CRM plugin to an external web services:
Web service code :
Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.Data
Imports System.Data.Sql
' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
' <System.Web.Script.Services.ScriptService()> _
<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Public Class WebService
Inherits System.Web.Services.WebService
<WebMethod()> _
Public Function IsContact(ByVal ID As String) As String
Dim ConnectionString As String = "Data Source=CRM\SQL;Initial Catalog=Demo_DB;User ID=sa;Password=P#$$S2016"
Dim SqlConn As New SqlClient.SqlConnection
Dim SQlCmd As New SqlClient.SqlCommand
Dim SQLDr As SqlClient.SqlDataReader
SqlConn.ConnectionString = ConnectionString
SQlCmd.Connection = SqlConn
SQlCmd.CommandText = "SELECT [fullname] FROM [dbo].[TContact] WHERE [ContactId] ='" & ID & "'"
Try
SqlConn.Open()
SQLDr = SQlCmd.ExecuteReader
If SQLDr.Read() Then
Return SQLDr.Item(1).ToString
Else
Return False
End If
SqlConn.Close()
Catch ex As Exception
SqlConn.Close()
Return ""
End Try
End Function
End Class
