i have two string array
string[] oldname = ["arun","jack","tom"];
string[] newname = ["jack","hardy","arun"];
here i want compare these two string arrays to get these distinct values separately like :
oldname = ["tom"];
newname = ["hardy"];
how to achieve these ...
string[] oldNameDistinct = oldname.Where(s => !newname.Contains(s)).ToArray();
string[] newNameDistinct = newname.Where(s => !oldname.Contains(s)).ToArray();
Let the two arrays were defined like the following:
string[] oldname = new[] { "arun", "jack", "tom" };
string[] newname = new string[] { "jack", "hardy", "arun" };
Then you can use the Extension method .Except to achieve the result that you are looking for. Consider the following code and the working example
var distinctInOld = oldname.Except(newname);
var distinctInNew = newname.Except(oldname);
Try this :
string[] oldname = new string[] { "arun", "jack", "tom" };
string[] newname = new string[] { "jack", "hardy", "arun" };
List<string> distinctoldname = new List<string>();
List<string> distinctnewname = new List<string>();
foreach (string txt in oldname)
{
if (Array.IndexOf(newname, txt) == -1)
distinctoldname.Add(txt);
}
foreach (string txt in newname)
{
if (Array.IndexOf(oldname, txt) == -1)
distinctnewname.Add(txt);
}
//here you can get both the arrays separately
Hope this help :)
string[] oldname = new []{"arun","jack","tom"};
string[] newname = new []{"jack","hardy","arun"};
// use linq to loop through through each list and return values not included in the other list.
var distinctOldName = oldname.Where(o => newname.All(n => n != o));
var distinctNewName = newname.Where(n => oldname.All(o => o != n));
distinctOldName.Dump(); // result is tom
distinctNewName.Dump(); // result is hardy
