用VaultSharp在C#中读取地下室秘密

Question

VaultSharp包似乎包含了我想要的所有内容，并且有很好的文档。我试图使用VaultSharp包从Vault服务器读取我们的秘密。但我生锈的C#在下面的"Secret<SecretData> kv2Secret = await vaultClient.V1.Secrets.KeyValue.V2.ReadSecretAsync("/secret/my_corp/my_app/dev/db_creds");“行上拦住了我，并发出了错误信息：

“等待”操作符只能在异步方法中使用。考虑使用“异步”修饰符标记此方法，并将其返回类型更改为“Task”。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using VaultSharp;
using VaultSharp.V1.AuthMethods.AppRole;
using VaultSharp.V1.AuthMethods;
using VaultSharp.V1.Commons;
using VaultSharp.V1.AuthMethods.Token;

namespace VaultConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var vaultUrl = "https://vault-server.url.com:443";
            Program.by_token(vaultUrl);

        }

     
       static  void by_token(string vaultUrl)
        {
            // Initialize one of the several auth methods.
            IAuthMethodInfo authMethod = new TokenAuthMethodInfo("s.R2gFHDiup5wCeHHksfc2zKUN");

            // Initialize settings. You can also set proxies, custom delegates etc. here.
            var vaultClientSettings = new VaultClientSettings(vaultUrl, authMethod);

            IVaultClient vaultClient = new VaultClient(vaultClientSettings);

            // Use client to read a key-value secret.
           Secret<SecretData> kv2Secret = await vaultClient.V1.Secrets.KeyValue.V2.ReadSecretAsync("/secret/my_corp/my_app/dev/db_creds");
        }

    }
}

错误就是告诉你你需要知道的事情。尽管我们推断：

“等待”操作符只能在异步方法中使用。考虑使用‘异步’修饰符标记此方法，并将其返回类型更改为'Task'。

static async Task Main(string[] args)
{
    var vaultUrl = "https://vault-server.url.com:443";
    await Program.by_token(vaultUrl);
}

 
static async Task by_token(string vaultUrl)
{
    ...
    Secret<SecretData> kv2Secret = await vaultClient.V1.Secrets.KeyValue.V2.ReadSecretAsync("/secret/my_corp/my_app/dev/db_creds");
}

此时，您应该对异步和等待模式进行一些研究：
