Remove Method (IPFilters)

Summary

Removes the IP filter at the specified index.

Syntax

C++

public void Remove( 
   int index 
)

Public Sub Remove( _ 
   ByVal index As Integer _ 
)

public: 
void Remove(  
   int index 
)

Parameters

index
Zero-based index of the IP filter to remove.

Remarks

This function toggles the "allow" permission for the specified IP filter and combines the new entry with the existing collection. This has the effect of deleting the entry. The resulting collection is always a normalized list covering the complete IP address range. Call Count to obtain the resulting collection's IP filter count. If the method fails, an error is raised. For more information, refer to the Error Codes.

Example

using Leadtools; 
using Leadtools.MediaStreaming; 
 
 
public Server _server = null; 
public bool _result = false; 
 
public void SetLocalNetworkFilterExample() 
{ 
   try 
   { 
      // this routine will set up an IP filter that only allows local network connections 
 
 
 
      string ipfirst = ""; 
      string iplast = ""; 
 
      // create an instance of the server object 
      _server = new Leadtools.MediaStreaming.Server(); 
 
      // retrieve a copy of the IP Filters 
      IPFilters filters = _server.GetIPFilters(); 
 
      // create a full range blacklist 
      // equivalent to filters.Add("0.0.0.0", "255.255.255.255", false); 
 
      // create a full range whitelist 
      filters.Reset(); 
 
      // invert the single whitelist filter to create the blacklist 
      filters.Remove(0); 
 
      { 
         // obtain the server's IP address and create the filter range 
         NetworkProperties props = _server.GetNetworkProperties();

      _result = true;
