無法從 IEnumerable 轉換<string>燒焦

Question

private async Task<string> GenerateQueryAsync(string month, IEnumerable<string> includedUsers)
{
    var queryTemplate = await _settingsService.GetAsync("Sat_Retest_Query_Template");
    var sb = new StringBuilder(queryTemplate.Value);
    sb.Replace("{startDate}", month + "/01");
    sb.Replace("{endDate}", GetNextYearMonth(month) + "/01");
    sb.Replace("{includedUsers}", includedUsers);
    return sb.ToString();
}

我該如何解決

無法從System.Collections.Generic.IEnumerable<string>轉換為char

對於IncludeUsers ？

Answer 1

您需要將 IEnumerable<string> 轉換為對您的情況有意義的某種形式的字符串。

例如，這顯示了如何將其轉換為 CSV，例如 ["one", "two"] 變為 "one, two"

var includedUsersCsv = string.Join(", ", includedUsers);
sb.Replace("{includedUsers}", includedUsersCsv);
