int myInteger = 1; Step 2 Declare the string variable. A string variable needs to be defined to save the converted integer. You can't save a string to a declared integer variable, so there needs to be a second
Cannot convert from 'Object to Int' Cannot convert int[] to object[] Cannot convert lambda expression to type 'System.Threading.Tasks.Task' Cannot convert null to 'int' because it is a value type--need help Cannot convert string[] to string in foreach loop Cannot convert type 'System.Col...
接著,這個緩衝區會傳遞至ToBase64String(Byte[])方法,以建立UUencoded (base-64) 字串。 然後它會呼叫FromBase64String(String)方法來譯碼 UUencoded 字元串,並呼叫BitConverter.ToInt32方法,將每組四個字節(32 位整數的大小)轉換成整數。 範例的輸出會顯示原始數位已成功還原。

string username=cmd.ExecuteScalar().ToString(); 除非你认为cmd执行后,肯定至少有一行数据,否则这里就会出错。 又或者select id from usertable where username=@name这样的sql语句,如果找不到记录,那么ExecuteScalar则会返回null,所以千万不要 int userid=Convert.ToInt32(cmd.ExecuteScalar()); ...
