从查询C#中删除最后一个逗号,可以使用以下方法:
string query = "SELECT * FROM table_name WHERE column_name = value;";
string newQuery = query.Substring(0, query.LastIndexOf(','));
string query = "SELECT * FROM table_name WHERE column_name = value;";
string newQuery = Regex.Replace(query, ",(?=[^,]*$)", "");
string query = "SELECT * FROM table_name WHERE column_name = value;";
string[] queryParts = query.Split(',');
string newQuery = string.Join(",", queryParts.Take(queryParts.Length - 1)) + queryParts.Last();
这些方法都可以有效地从查询C#中删除最后一个逗号。
