Keeping Query Params in a Hashtable

Demonstrates how to use a Chilkat Hashtable to hold query params and re-emit as a query param string.

Note: The ToQueryString method was added in Chilkat v9.5.0.92.

C#

bool success = false;

Chilkat.Hashtable ht = new Chilkat.Hashtable();

//  Add name/value pairs from an existing query param string where the values are already URL encoded.
string qp = "txt=this%20is%20a%20test&color=blue&fruits=apples%26oranges";
success = ht.AddQueryParams(qp);

//  Add some additional name/value pairs.
ht.AddStr("name","Jack Sparrow");
ht.AddStr("movie","Pirates of the Carribean");

//  Iterate over the hash table to show what we have..

Chilkat.StringTable keys = new Chilkat.StringTable();
ht.GetKeys(keys);
int numKeys = keys.Count;
string key;
string val;
int i = 0;
while (i < numKeys) {
    key = keys.StringAt(i);
    val = ht.LookupStr(key);
    Debug.WriteLine(key + " = " + val);
    i = i + 1;
}

//  Output for the above loop:

//  color = blue
//  name = Jack Sparrow
//  fruits = apples&oranges
//  txt = this is a test
//  movie = Pirates of the Carribean

//  Get all name/value pairs as a query parm string with values URL encoded
qp = ht.ToQueryString();
Debug.WriteLine(qp);

//  Result:
//  color=blue&name=Jack%20Sparrow&fruits=apples%26oranges&txt=this%20is%20a%20test&movie=Pirates%20of%20the%20Carribean
