In this Blog we are going to see, How to Remove item from the Dictionary Collection.
Step 1:
Adding items to Dictionary as KeyValuePair
Dictionary<int,
string> dic = new
Dictionary<int,
string>();
dic.Add(1, "Lajapathy");
dic.Add(2, "Parthiban");
dic.Add(3, "AnandBabu");
dic.Add(4, "Sathiya");
Step 2:
Displaying the Dictionary Items
foreach (KeyValuePair<int, string>
tempDic in dic)
{
Response.Write("Key :" +
tempDic.Key + " value :" +
tempDic.Value + "<br/>");
}
Step 2:
Removing item from the Dictionary
bool isRemoved = dic.Remove(2);
Response.Write(isRemoved + "<br/>");
Step 3:
Displaying Items after Removing
foreach (KeyValuePair<int, string> tempDic
in dic)
{
Response.Write("Key :" +
tempDic.Key + " value :" +
tempDic.Value + "<br/>");
}

Key :2 value :Parthiban
Key :3 value :AnandBabu
Key :4 value :Sathiya
