在較早的 SQL 版本,要檢測 TSQL 是否有發生執行錯誤,都只能透過判斷 @@ERROR 全域變數,直到 SQL2005 才新增了 TRY...CATCH 這個結構化的例外處理功能。 它採用和程式語言中的 TRY...CATCH 類似的語法,在 TRY 區塊內放的是一般陳述式,CATCH 區塊內放的是錯誤處理的陳述式。
使用 TRY...CATCH 結構,若執行的 TSQL 發生了錯誤,錯誤訊息將不會傳到呼叫端,除非透過 RAISERROR 再送出錯誤訊息。
取得錯誤訊息的函式:
當使用 TRY...CATCH 時,你可以在 CATCH 區塊中使用以下函式以取得與錯誤訊息相關的資訊:
ERROR_NUMBER :發生錯誤的錯誤代碼
ERROR_MESSAGE :發生錯誤的錯誤訊息
ERROR_SEVERITY :發生錯誤的錯誤層級
ERROR_STATE :發生錯誤的錯誤狀態
ERROR_PROCEDURE :發生錯誤的程序名稱
ERROR_LINE :發生錯誤的行數
BEGIN TRY
INSERT Emp(EmpName, DepNo) Values (@EmpName, 1)
INSERT Emp(EmpName, DepNo) Values (@EmpName, 1)
END TRY
BEGIN CATCH
PRINT '錯誤代碼:' + cast(ERROR_NUMBER() as varchar(5)) + char(13) +
'錯誤訊息:' + ERROR_MESSAGE()
RAISERROR('資料寫入錯誤',16,10)
END CATCH;
以上函式,若不是在 CATCH 區塊中使用,都將回傳 NULL 。

HttpClient
提出 HTTP 要求
若要提出 HTTP 要求,您可以呼叫下列任何 API:
HTTP 方法 API
GET HttpClient.GetAsync
GET HttpClient.GetByteArrayAsync
GET HttpClient.GetStreamAsync
GET HttpClient.GetStringAsync
POST HttpClient.PostAsync
PUT HttpClient.PutAsync
PATCH HttpClient.PatchAsync
DELETE HttpClient.DeleteAsync
HttpClient.SendAsync USER SPECIFIED 要求表示 SendAsync 方法接受任何有效的 HttpMethod

方法2. 通过命令提示符删除记录
在方法1中我们可以手动将远程桌面连接历史删除,如果觉得太麻烦或太费时间,我们也可以通过命令提示符删除远程桌面连接记录。
步骤1. 按“Win + R”键,然后输入“CMD”打开命令提示符。
步骤2. 然后依次输入以下命令,并在每个命令输入完成按下回车键。
reg delete “HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default” /va /f
reg delete “HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Servers” /f
reg add “HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Servers”
