示例1: DivideByZeroException
// Add the following directive to the file:
// using System.Linq.Expressions;
// A TryExpression object that has a Catch statement.
// The return types of the Try block and all Catch blocks must be the same.
TryExpression tryCatchExpr =
Expression.TryCatch(
Expression.Block(
Expression.Throw(Expression.Constant(new DivideByZeroException())),
Expression.Constant("Try block")
),
Expression.Catch(
typeof(DivideByZeroException),
Expression.Constant("Catch block")
)
);
// The following statement first creates an expression tree,
// then compiles it, and then runs it.
// If the exception is caught,
// the result of the TryExpression is the last statement
// of the corresponding Catch statement.
Console.WriteLine(Expression.Lambda<Func<string>>(tryCatchExpr).Compile()());输出：
Catch block
