用法

let
    input = 100,
    divisor = 0,
    result = try if divisor = 0 then
        error Error.Record(
            "DivideByZero",

        input / divisor
in
    result

输出

[
    HasError = true,
    Error =
    [
        Reason = "DivideByZero",
        Message = "You attempted to divide by zero.",
        Detail = null,
        Message.Format = null,
        Message.Parameters = null,
        ErrorCode = null
    ]
]

示例 2

            "CustomerNotFound",
            Text.Format("Customer ID #{0} wasn't found.", {CustomerId}),
            "Customer doesn't exist.",
            {
                Text.Format("Invalid ID = #{0}", {CustomerId}),
                "Valid IDs: https://api.contoso.com/customers"
            },
            "ERR404"
        )
    else CustomerId
in
    result

输出

[
    HasError = true,
    Error = [ 
        Reason = "CustomerNotFound",
        Message = "Customer ID 12345 wasn't found.",
        Detail = "Customer doesn't exist.",
        Message.Format = "Customer ID 12345 wasn't found.",
        Message.Parameters = {
            "Invalid ID = 12345",
            "Valid IDs: https://api.contoso.com/customers"
