❌ The following approach is NOT recommended for Microsoft Azure Blob Storage because the file's Stream content is copied into a MemoryStream in memory ( memoryStream) before calling UploadBlobAsync: var memoryStream = new MemoryStream() īrowserFile.OpenReadStream().CopyToAsync(memoryStream) Īwait blobContainerClient.UploadBlobAsync( ❌ The following approach is NOT recommended because the file's Stream content is read into a String in memory ( reader): var reader =Īwait new StreamReader(browserFile.OpenReadStream()).ReadToEndAsync() In the following examples, browserFile represents the uploaded file and implements IBrowserFile: If you need access to a Stream that represents the file's bytes, use IBrowserFile.OpenReadStream. Instead, consider copying file bytes to an external store, such as a blob or a file on disk. These approaches can result in performance and security problems, especially in Blazor Server. For example, don't copy file bytes into a MemoryStream or read as a byte array. The maxAllowedSize parameter of OpenReadStream can be used to specify a larger size if required.Īvoid reading the incoming file stream directly into memory. This limit prevents developers from accidentally reading large files in to memory. Reading one file or multiple files larger than 512,000 bytes (500 KB) results in an exception. OpenReadStream enforces a maximum size in bytes of its Stream. For more information, see the File streams section. To read data from a user-selected file, call IBrowserFile.OpenReadStream on the file and read from the returned stream. So create another file gauss_sum.hpp and put the declarations there.In the preceding example, the element's _bl_2 attribute is used for Blazor's internal processing. We are calling such files header files and typically set their extension to hpp. Instead, its content should be read and inserted into the file it is called from. This file serves not as a typical C++ source file. Hence, we would like to have a file containing all those declarations which can easily be included into the source file where we want to call the functions. But it becomes a cumbersome process for many functions and more complicated projects. If we are using only one or two functions, this may not be a big problem. Now it becomes clear that every time we want to call one of the functions in gauss_sum.cpp in a different source file, we have to state the according declarations of these functions at the beginning of this source file.

Removing the Need of Manual Declaration ¶ Looking back at the Fibonacci Project ¶įirst, let us start by creating a new project. We will talk about this process in more detail in the next lessons. For larger projects with multiple programmers, this opens up the possibility to work in parallel on different parts of the code. Furthermore, we are able to change the implementation of a function without the user of this function recognizing it.
#Input file format to gausssum code#
So we can put the declaration of a function everywhere to make sure the code following is able to call the according function. Declarations are allowed to appear multiple times as long as they are providing the same interface. This is called the One Definition Rule (ODR). The definition of a function must appear exactly once in the project. For complex projects, this is not always possible.

So why are we even dealing with declarations? As we have seen in the second lecture, a call to a function that is only given by a definition has to appear after the respective definition. As a consequence, the definition is self-consistent and C++ does not need the declaration of the function. In C++, the definition of a function must include its interface because otherwise the function could not be properly implemented as the definition would not know about the types of input and output variables.
