我正在尝试将此字节数组插入SQL Server数据库,列数据类型为varbinary,这是我在C#中的代码SqlParameter param = new SqlParameter("@buffer", SqlDbType.VarBinary, 8000); param.Value = buffer;string _query = "INSERT INTO [dbo].[Files] (FileID, Data, Length) VALUES ('" + uID + "','" + buffer + "','" + buffer.Length + "')";using (SqlCommand comm = new SqlCommand(_query, conn)) {comm.Parameters.Add(param);try{c...
上测试代码using System;public static class Program {public static void Main(string[] args){Console.WriteLine("{0}: {1} byte(s) scope:[{2}-{3}]",typeof(byte).Name.PadLeft(8), sizeof(byte).NumberPad(2),byte.MinValue.NumberPad(32, true), byte.MaxValue.NumberPad(32));Console.WriteLine("{0}: {1} byte(s) scope:[{2}-{3}]",typeof(sbyte).Name.PadLeft(8), sizeof(sbyte).NumberPad(2),sbyte.MinValue.NumberPad(...
我需要打开一个Microsoft Word文档,替换一些文本然后转换为pdf字节数组.我已经创建了代码来执行此操作,但它涉及将pdf保存到磁盘并将字节读回内存.我想避免在磁盘上写任何东西,因为我不需要保存文件. 以下是我到目前为止所做的代码……using System.IO; using Microsoft.Office.Interop.Word;public byte[] ConvertWordToPdfArray(string fileName, string newText) {// Temporary path to save pdfstring pdfName = fileName.Subst...
