Error message

未知的角色信息分类：{rawCategory}

What it means

Thrown by ParseCategories when splitting the categories string by ';' yields a token that doesn't match any known category. Valid categories are '属性' (Attribute), '武器' (Weapon), '天赋' (Talent). Any other token (including typos or English names) triggers this ArgumentException.

Solutions

1. Use only valid category names: '属性', '武器', '天赋' (semicolon-separated).
2. Check for typos or encoding issues in the category string.
3. Remove extra semicolons or empty tokens from the input.
4. Pass null for all categories if unsure.

Example fix

// before (wrong)
await dev.GetMultiCharacters(['钟离'], '属性;Talent');
// after
await dev.GetMultiCharacters(['钟离'], '属性;天赋');

// Validate category tokens before calling
var validCategories = new HashSet<string> { "属性", "武器", "天赋" };
if (categories != null)
{
    foreach (var token in categories.Split(';'))
    {
        if (!validCategories.Contains(token.Trim()))
        {
            throw new ArgumentException($"Invalid category: {token}. Valid: 属性, 武器, 天赋");
        }
    }
}

static bool IsValidCategoryString(string? categories)
{
    if (categories == null) return true;
    if (string.IsNullOrWhiteSpace(categories)) return false;
    var valid = new HashSet<string> { "属性", "武器", "天赋" };
    return categories.Split(';').All(t => valid.Contains(t.Trim()));
}

try
{
    await dev.GetMultiCharacters(names, categories);
}
catch (ArgumentException ex) when (ex.Message.Contains("未知的角色信息分类"))
{
    // Use only valid categories: 属性, 武器, 天赋
}

When it happens

Trigger: Called from ParseCategories. categories.Split(';') produces a token that, after trimming, doesn't match '属性', '武器', or '天赋' in the switch expression default arm.

Common situations: Typo in category name (e.g. '属' instead of '属性'); using English names (e.g. 'Talent') instead of Chinese; extra semicolons producing empty tokens that should have been filtered; game version added new categories not yet supported.
