WebService Access Encryption-soapheader

Go WebService head encryption, you canWebService set Access user name and password, enhance the security of WebService so that webservice can only be used by authorized users.
Specific implementation steps:
1. define a SoapHeader derived class to implement WebService access validation [CSharp]View Plaincopy

2, define the need to verify the WebService.

66. {
70. string msg = "";
74. //Verify that you have access to

80. {
84. return-1; //Return error message
88. }
92. return ProductId;
94. }
96. }

3. Client Call Method
The reference WebService defines the WebService name as : MyService
