Problem in populating a dictionary using Enumerable.Range()


If I do

for (int i = 0; i < appSettings.Count; i++)
{
   string key = appSettings.Keys[i];
   euFileDictionary.Add(key, appSettings[i]);
}

It is working fine.

When I am trying the same thing using

Enumerable.Range(0, appSettings.Count).Select(i =>
{
   string Key = appSettings.Keys[i];
   string Value = appSettings[i];
   euFileDictionary.Add(Key, Value);
}).ToDictionary<string,string>();

I am getting a compile time error

The type arguments for method 'System.Linq.Enumerable.Select(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly.

Any idea?

Using C#3.0

Thanks


Solution

  • Enumerable.Range(0, appSettings.Count).Select(i =>
    new  
    {   
       Key = appSettings.Keys[i],
       Value = appSettings[i]
    })
    .ToDictionary(x => x.Key, x => x.Value);
