Concat - 1
This C# example uses the LINQ Concat method with a dynamic expression to create one sequence that contains each array's values, one after the other.
LINQ
private void uiConcat_1_LINQ_Click(object sender, EventArgs e) int[] numbersA = {0, 2, 4, 5, 6, 8, 9}; int[] numbersB = {1, 3, 5, 7, 8}; var allNumbers = numbersA.Concat(numbersB); Console.WriteLine("All numbers from both arrays:"); foreach (var n in allNumbers) { Console.WriteLine(n); }
LINQ Execute
int[] numbersA = {0, 2, 4, 5, 6, 8, 9}; int[] numbersB = {1, 3, 5, 7, 8}; var allNumbers = numbersA.Execute<IEnumerable<int>>("Concat(numbersB)", new {numbersB}); Console.WriteLine("All numbers from both arrays:"); foreach (var n in allNumbers) { Console.WriteLine(n.ToString()); }
Result
All numbers from both arrays:
0

LINQ
private void uiConcat_2_LINQ_Click(object sender, EventArgs e) { var customers = My.GetCustomerList(); var products = My.GetProductList(); var customerNames = from c in customers select c.CompanyName; var productNames = from p in products select p.ProductName; var allNames = customerNames.Concat(productNames); var sb = new StringBuilder(); sb.AppendLine("Customer and product names:"); foreach (var n in allNames) { sb.AppendLine(n); } My.Result.Show(My.LinqResultType.Linq, uiResult, sb); }
LINQ Execute
private void uiConcat_2_LINQ_Execute_Click(object sender, EventArgs e) { var customers = My.GetCustomerList(); var products = My.GetProductList(); var customerNames = from c in customers select c.CompanyName; var productNames = from p in products select p.ProductName; var allNames = customerNames.Execute<IEnumerable<string>>("Concat(productNames)", new {productNames}); var sb = new StringBuilder(); sb.AppendLine("Customer and product names:"); foreach (var n in allNames) { sb.AppendLine(n); } My.Result.Show(My.LinqResultType.LinqExecute, uiResult, sb); }
