问题描述
我有一个SQL CLR DLL我要部署,而是发现你可以嵌入字节流/ varbinary_literal / varbinary_ex pression /组装位到一个文本文件来解决包装一个DLL,使凌乱麻烦确保它是可访问的 CREATE ASSEMBLY命令。
I have a SQL CLR dll I want to deploy, but have found you can embed the byte stream/varbinary_literal/ varbinary_expression/assembly bits into a text file to get around the messy hassle of packaging a DLL and making sure it's accessible for the CREATE ASSEMBLY command.
但我还没有找到是如何得到的字节流/ varbinary_literal / varbinary_ex pression /装配位值。我还没有发现任何一致的术语,什么我一直在寻找使用加载()
。
But what I have yet to find is how to get that byte stream/varbinary_literal/ varbinary_expression/assembly bits value. I haven't found any consistent terminology, and what I keep finding in using Load()
.
帮助?
推荐答案
这是该DLL的只是一个十六进制再presentation。该位应该做的伎俩:
It's just a hex representation of the dll. This bit should do the trick:
static string GetHexString(string assemblyPath)
{
if (!Path.IsPathRooted(assemblyPath))
assemblyPath = Path.Combine(Environment.CurrentDirectory, assemblyPath);
StringBuilder builder = new StringBuilder();
builder.Append("0x");
using (FileStream stream = new FileStream(assemblyPath,
FileMode.Open, FileAccess.Read, FileShare.Read))
{
int currentByte = stream.ReadByte();
while (currentByte > -1)
{
builder.Append(currentByte.ToString("X2", CultureInfo.InvariantCulture));
currentByte = stream.ReadByte();
}
}
return builder.ToString();
}
您应该使用生成的字符串,像这样:
You should use the resulting string like so:
string hexString = GetHexString(assemblyPath);
string sql = "CREATE ASSEMBLY [" + assemblyName + "] FROM " + hexString +
" WITH PERMISSION_SET = " + somePermissionSet;
