c# – 如何将String []转换为IDictionary？

Dictionary<string,string> ArrayToDict(string[] arr)
{
    if(arr.Length%2!=0)
        throw new ArgumentException("Array doesn't contain an even number of entries");
    Dictionary<string,string> dict=new Dictionary<string,string>();
    for(int i=0;i<arr.Length/2;i++)
    {
      string key=arr[2*i];
      string value=arr[2*i+1];
      dict.Add(key,value);
    }
    return dict;
}
