TARGET：执行Azure功能教程并复制代码，但在VS2017上本地执行时遇到了一些错误。我感谢你的帮助。

错误1 - 与Run：

相关

CS0116命名空间不能直接包含诸如字段或方法UploadToBlobFunctionApp之类的成员 C：\ AzureFunctions \ UploadToBlobFunctionApp \ UploadToBlobFunctionApp \ UploadToBlobFunction.cs 45 Active

错误3 - 与await CreateBlob相关：

CS0103名称＆＃39; CreateBlob＆＃39;当前上下文中不存在UploadToBlobFunctionApp C：\ AzureFunctions \ UploadToBlobFunctionApp \ UploadToBlobFunctionApp \ UploadToBlobFunction.cs 36活动

代码Function.cs：

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
HttpStatusCode result;
string contentType;

result = HttpStatusCode.BadRequest;

contentType = req.Content.Headers?.ContentType?.MediaType;

if (contentType == "application/json")
{
    string body;

    body = await req.Content.ReadAsStringAsync();

    if (!string.IsNullOrEmpty(body))
    {
        string name;

        name = Guid.NewGuid().ToString("n");

        await CreateBlob(name + ".json", body, log);

        result = HttpStatusCode.OK;
    }

await container.CreateIfNotExistsAsync();

blob = container.GetBlockBlobReference(name);
blob.Properties.ContentType = "application/json";

using (Stream stream = new MemoryStream(Encoding.UTF8.GetBytes(data)))
{
    await blob.UploadFromStreamAsync(stream);
}
}

Answer 1

您正在引用的示例是使用脚本函数（csx文件）。它们主要用于直接在Azure门户中编辑代码。

我认为您正在尝试使用csproj和cs文件创建预编译的应用程序。在这种情况下，您的代码应该是有效的C＃，即所有方法都应该在类中。

查看this example。

您还可以使用属性来标记您的功能和触发器，而不是手动创作function.json，请参阅示例here。

命名空间不能直接包含Azure功能应用程序中的成员
