See more:

i have one collection like
strnameCollection

[0]={number:12, name:"abc"}
[1]={number:13, name:"abc, cdf"}
[2]={number:14, name:"tre"}
[3]={number:15, name:"iuj"}

one more collection name like strcollection

[0]={number:12, value:"zzzz"}
[1]={number:13, value:"abc, tyu"}

USE LinQ

do i need to compare both collection and get count for matching records. example "abc" is matching and existing 2 times in strnameCollection.

My Result should be

{number:12, name:"abc"}
{number:13, name:"abc,cdf"}

i want to make using Linq and not foreach loop.

Below is your solution.

C#

var strCollection1 = new[] {
               new{number=12, name="abc"},
               new{number=13, name="abc, cdf"},
               new{number=14, name="tre"},
               new{number=15, name="iuj"}
           };

           var strCollection2 = new[] {
               new{number=12, name="abc"},
               new{number=13, name="abc, cdf"},
           };

           var joined = from x1 in strCollection1
                        join x2 in strCollection2
                           on new { x1.name, x1.number } equals
                              new { x2.name, x2.number }
                        select x1;

           foreach (var item in joined)
           {
               Console.WriteLine("{number=" + item.number + ",name=" + item.name + "}");
           }

Solution 2

What about this:

C#

var common = strCollection1.Intersect(strCollection2);
Console.WriteLine(common.Count());

...using the two collections from Solution 1.
