摘要：1、创建事务的结构SqlConnection sqlConnection = new SqlConnection(); ...初始化连接 // 开启事务 SqlTransaction sqlTransaction = sqlConnection.BeginTransaction(); // 将事务应用于Command SqlCommand sqlCommand = new SqlCommand(); sqlCommand.Connection = sqlConnection; sqlCommand.Transaction = sqlTransaction; try { //... 阅读全文

摘要：1.字符串转换成字节数组byte[] array = Encoding.UTF8.GetBytes("你好");2.字节数组转换成base64字符串string base64 = Convert.ToBase64String(array);3.base64String转换成字节数组byte[] bitArray = Convert.FromBase64String(base64String);首先要明白它们本身是由什么组成的：流：二进制字节：无符号整数字符：Unicode编码字符字符串：多个Unicode编码字符那么在.net下它们之间如何转化呢？一般是遵守以下规则：流-& 阅读全文
