Compiler Error CS1946
An anonymous method expression cannot be converted to an expression tree.
An anonymous method represents a set of statements but an expression tree must not contain a statement. Therefore an anonymous method cannot be represented by an expression tree.
To correct this error
- Change the anonymous method to a lambda expression.
Example
The following example generates CS1946:
// cs1946.cs
using System;
using System.Linq.Expressions;
public delegate void D();
class Test
{
static void Main()
{
Expression<D> tree = delegate() { }; //CS1946
// Try using a lambda expression instead.
// Expression<D> tree = (x) => x + 1;
}
}
