Write Binary Data A way to store data in C# is towrite to a binary file. A binary file allows developers to write data types such as int, bool, string, etc to a file. A binary file can then be read to retrieve those values. Binary files are useful for saving application settings fo...

在 C 中,您不能像在 C 中那样假设对象的内容。例如,std::string 通常包含指针、分配器、字符串长度和/或前几个字符。它肯定不会保存您从 string::data() 获得的整个 char[]。如果你有一个 std::string[3],三个 sring::data() 数组将(几乎可以肯定)是不连续的,所以你将需要三次写入——每次调用只能...
The Write Binary File block takes the video data from a Simulink® model and exports it to a binary file. This block produces a raw binary file with no header information. It has no encoded information providing the data type, frame rate, or dimensionality. The video data for this block...

i have a record of 55 16 bit words that i want to write to a file. the to file block converts to double and limits at 10**8 elements. these are 1200Hz records and want to make it binary to reduce size. using simulink only....
