物品原型表存在无法读取的记录。

Error message

物品原型表存在无法读取的记录。

What it means

Thrown as InvalidDataException by LoadWeaponNames inside the row-reading loop when parser.ReadFields() returns null for a data row (after headers were already read successfully). This indicates the CSV has malformed content mid-file that TextFieldParser cannot parse into fields — typically a quoting or delimiter inconsistency on a specific line.

Solutions

1. Inspect item.csv line-by-line around the suspected position for quoting or comma issues.
2. Restore item.csv from a clean repository copy.
3. If the CSV is generated, fix the export logic to properly quote fields containing commas.

Example fix

null

null

null

while (!parser.EndOfData)
{
    try { var fields = parser.ReadFields() ?? throw new InvalidDataException(); rows.Add(fields); }
    catch (Exception ex) { /* log line number, skip or abort depending on tolerance */ }
}

When it happens

Trigger: A data row in item.csv has unmatched quotes, an invalid escape sequence, or a delimiter configuration that makes TextFieldParser fail to produce fields for that line.

Common situations: Hand-editing item.csv introduced a syntax error in one row. A data export tool produced a row with embedded commas inside unquoted fields. The file has mixed encodings causing byte-level corruption on certain rows.
