Creates an empty expression that has Void type.
Assembly: System.Core (in System.Core.dll)
The following code example shows how to create an empty expression and add it to a block expression.
// Add the following directive to your file: // using System.Linq.Expressions; // This statement creates an empty expression. DefaultExpression emptyExpr = Expression.Empty(); // The empty expression can be used where an expression is expected, but no action is desired. // For example, you can use the empty expression as the last expression in the block expression. // In this case the block expression's return value is void. var emptyBlock = Expression.Block(emptyExpr);
