Split list into sublists using LINQ in C#.NET

Here is the sample LINQ C# code to split list into sublists

public static List<List<T>>Split<T>( this List <T> sourceint NumberOfGroup )
        {
            return source
                .Select((x i)=>new Index iValue x })
                .GroupBy(x => x.Index NumberOfGroup )
                .Select(x => x.Select (v => v.Value).ToList())
                .ToList();

        }
The idea is to first group the elements by indexes. Dividing by NumberOfGroup as the effect of grouping them into groups of NumberOfGroup. Then convert each group to a list and the IEnumerable of List to a List of Lists

Similar to list we can divide dictionary also in sub-dictionaries. Here is the sample code

public static List< Dictionary<T1, T2>>Split< T1T2 >(this Dictionary<T1, T2> source int NumberOfGroup)
        {
            return source
                .Select((x i) => new Index iValue x })
                .GroupBy(x => x.Index NumberOfGroup )
                .Select(x => x.Select (v => v.Value ).ToDictionary( z => z.Key z => z.Value ))
                .ToList();
        }




Other useful LINQ operations:


Remove element from array :
int[] numbers = { 1, 3, 4, 9, 2 };
int numToRemove = 4;
numbers = numbers.Where(val => val != numToRemove).ToArray();

Show Image on canvas HTML5

Here is the sample code to select image from system and display it on html5 canvas and javascript: <input type= "file" id= "selectedImage" /> <canvas id= "myCanvas" width= "500" height= "500" > </canvas> Javascript code: $( "#selectedImage" ).change( function (e) { var URL = window .URL; var url = URL.createObjectURL(e.target.files[ 0 ]); img.src = url; img.onload = function () { var canvas = document .getElementById( "myCanvas" ); var ctx = canvas.getContext( "2d" ); var imgSize = calculateAspectRatioFit(img.width, img.height, canvas.clientWidth, canvas.clientHeight); ctx.clearRect( 0 , 0 , canvas.width, canvas.height); ctx.drawImage(img, 0 , 0 , imgSize.width, imgSize.height); } }); function calculateAspectRatioFit(srcWidth, srcHeight, maxWidth, maxHeight) { var ratio = Math .min(maxWi

Pass byte array from C# to C++ and vice-versa

Pass byte array from C# to C++                           If you want to pass a byte array to native DLL as parameter, you can use the Intptr to do this, please check the demo below. /C++ API code: TestDLL_API void TestArrayPara (BYTE * pArray, int nSize) { for ( int i= 0 ; i<nSize; i++) printf( "%d\n" , pArray[i]); } //C# code: class TestClass { [DllImport(@"TestDll.dll")] public static extern void TestArrayPara (IntPtr pArray, int nSize); public static void Test () { byte [] array = new byte [ 16 ]; for ( int i = 0 ; i < 16 ; i++) { array[i] = ( byte )(i + 97 ); } int size = Marshal.SizeOf(array[ 0 ]) * array.Length; IntPtr pnt = Marshal.AllocHGlobal(size); try { // Copy the array to unmanaged memory. Marshal.Copy(array, 0 , pnt, array

Display Tooltip for Combo Box item C#.NET Winforms

In windows form combo box control sometimes while adidng items dynamically we have items whose width is greater than width of combox box control. In this case for making UI more user friendly we can show tooltip over such item. Here is the sample C# code to display such tooltip:  Add a Tooltip control on the form.  Add following code : this . combo_box1 . DropDownStyle = System . Windows . Forms . ComboBoxStyle . DropDownList; this . combo_box1 . DrawMode = DrawMode . OwnerDrawFixed; this . combo_box1 . DrawItem += new DrawItemEventHandler(combo_box1_DrawItem); this . combo_box1 . DropDownClosed += new EventHandler(combo_box1_DropDownClosed); this . combo_box1 . MouseLeave += new EventHandler(combo_box1_Leave); void combo_box1_DrawItem( object sender, DrawItemEventArgs e) { if (e . Index < 0 ) { return ; } string text = combo_box1 . GetItemText(combo_box1 . Items[e . Index
