Consider the Array1= [ [ { name:"Joseph", age:23 }, { name:"linda", age:22 }], [{ name:"bob", age:22 }, { name:"suzan", age:22 }] ] ;

var Result369=Array1.SelectMany(); The Result369 array will looks like this:

[ { name:"joseph", age:23 }, { name:"linda", age:22 }, { name:"bob", age:22 }, { name:"suzan", age:22 } ]
