match_inconformity

Error message

特征比对：以下功能补丁已经安装，请取消勾选！
已安装功能：【{string.Join("、", res.Item2)}】

What it means

matchNum was below the expected count and IsAllReplaced returned a non-empty set of already-replaced category names, but not all of them. FindChanges throws BusinessException('match_inconformity') listing those categories and telling the user to uncheck them.

Solutions

  1. Uncheck the categories named in the error message and retry.
  2. Alternatively, restore the DLL to start from a clean state, then re-select features.
Defensive patterns

Strategy: try-catch

Type guard

static bool IsBusinessException(Exception e, string code) => e is BusinessException b && b.ErrorCode == code;

static bool IsInconformity(Exception e) => IsBusinessException(e, "match_inconformity");

Try / catch

try
{
    modifier.ValidateAndFindModifyInfo(categories);
}
catch (BusinessException ex) when (ex.ErrorCode == "match_inconformity")
{
    // Message lists already-installed categories; prompt to uncheck them.
    MessageBox.Show(ex.Message);
}

Prevention

When it happens

Trigger: A subset of the selected feature categories is already patched in the DLL (search bytes gone, replace bytes present for those categories), while at least one selected category is not.

Common situations: User selects several features where some were installed in a previous run and others were not.
