array, hashtable(key, value) question

Unity Engine
1

Good Morning Guys,

Just a question about arrays and hashtables, I need to know how to get a value if I have the key, could anyone tell me that?

And one more question is:
How could I find out how often a value exists in one array?

so I have an array:

key[1] = "bla"
key[2] = "bla"
key[3] = "bla"

how to count this?

thanks to anyone.

best regards,

Part you want is:

arrayvariablename.length

You can either set or get the length from this, I believe?

Are you using C#? If that´s the case, use this

myHash.ElementAt(key)

The only way is counting:

int number = 0;
for (int i = 0; i < myArray.Length; i++)
{
    if (myArray[i] == value) number++;
}

You access items in an array thru its index, you access items in a hashtable thru its key…

Javascript example:

myhash = {"name":"John", "occupation":"programmer"};

Debug.Log( myhash["name"] ); //displays "John"

Iam using both js and C#, but thank you all, exactly what I need :wink:
