参数ItemNames不能包含空名称

Error message

参数ItemNames不能包含空名称

What it means

Thrown as ArgumentException by CountInventoryItemParam.Validate when the ItemNames list contains one or more entries that are null, empty, or whitespace-only. Even a single blank entry would cause downstream item matching to silently fail or match nothing, so the validator rejects the whole list upfront.

Solutions

1. Filter out blank entries before assigning: param.ItemNames = names.Where(n => !string.IsNullOrWhiteSpace(n)).ToList().
2. Validate source input (e.g., split result) and remove empty tokens immediately after splitting.
3. Add per-entry validation in the UI/script layer before constructing the param.

Example fix

// before
param.ItemNames = rawNames.Split(',').ToList(); // may contain ""
param.Validate(); // throws

// after
param.ItemNames = rawNames.Split(',')
    .Select(n => n.Trim())
    .Where(n => !string.IsNullOrWhiteSpace(n))
    .ToList();
param.Validate();

param.ItemNames = param.ItemNames
    .Where(n => !string.IsNullOrWhiteSpace(n))
    .Select(n => n.Trim())
    .ToList();

static bool ItemNamesAreClean(List<string> names)
    => names.All(n => !string.IsNullOrWhiteSpace(n));

try { param.Validate(); }
catch (ArgumentException ex) when (ex.Message.Contains("不能包含空名称")) { /* filter blanks, retry */ }

When it happens

Trigger: Setting ItemNames to a list like ["摩拉", "", "原石"] or ["摩拉", null, "原石"] — any whitespace entry triggers it because ItemNames.Any(string.IsNullOrWhiteSpace) returns true.

Common situations: A list was built from user input or split from a comma-separated string without trimming/filtering empties. A deserialization produced null or empty strings. An upstream filtering step was skipped.
