Expression.Increment Method (Expression)
Creates a UnaryExpression that represents the incrementing of the expression value by 1.
Assembly: System.Core (in System.Core.dll)
The following code example shows how to create an expression that represents an increment operation.
// Add the following directive to your file: // using System.Linq.Expressions; // This expression represents an increment operation. double num = 5.5; Expression incrementExpr = Expression.Increment( Expression.Constant(num) ); // Print out the expression. outputBlock.Text += incrementExpr.ToString() + "\n"; // The following statement first creates an expression tree, // then compiles it, and then executes it. outputBlock.Text += Expression.Lambda<Func<double>>(incrementExpr).Compile()() + "\n"; // The value of the variable did not change, // because the expression is functional. outputBlock.Text += "object: " + num + "\n"; // This code example produces the following output: // // Increment(5.5) // 6.5 // object: 5.5
