Question How to delete component?

I need to delete one component on selected object using a script. Here's an example:

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3. using System.Collections;
4. using System.Collections.Generic;
5.  
6. public class SampleWindow : EditorWindow
7. {
8.     Vector2 scrollView = Vector2.zero;
9.  
10.     [MenuItem("Window/Others/SampleWindow #W", false, 0)]
11.     static void OpenBSCMTools()
12.     {
13.         EditorWindow.GetWindow(typeof(SampleWindow));
14.     }
15.  
16.     void OnGUI()
17.     {
18.         scrollView = EditorGUILayout.BeginScrollView(scrollView);
19.         EditorGUILayout.BeginHorizontal();
20.         if (GUILayout.Button("Delete Box Collider", GUILayout.MinWidth(115), GUILayout.MaxWidth(135)))
21.         {
22.             if (Selection.activeGameObject != null)
23.             {
24.                 //Here I need to delete BoxCollider using a button
25.             }
26.         }
27.         if (GUILayout.Button("Delete Mesh Collider", GUILayout.MinWidth(115), GUILayout.MaxWidth(135)))
28.         {
29.             if (Selection.activeGameObject != null)
30.             {
31.                 //Here I need to delete MeshCollider using a button
32.             }
33.         }
34.         EditorGUILayout.EndHorizontal();
35.         EditorGUILayout.EndScrollView();
36.     }
37. }
