title: Remove Element From Array by String (text) instead of Index
body: <p>I want to remove the element form the array. Actually I don't know the the index of the element and want to remove through it's value. I have tried a lot but fail. This is the function which i used to add element in the Array</p>
  
  <pre><code>    string [] Arr;
      int i = 0;
      public void AddTOList(string ItemName)
      {
          Arr[i] = ItemName;
          i++;
      }
  </code></pre>
  
  <p>And I want to remove the element by the value. I know the below function is wrong but I want to explain what I want:</p>
  
  <pre><code>    public void RemoveFromList(string ItemName)
      {
          A["Some_String"] = null;
      }
  </code></pre>
  
  <p>Thanks</p>
