Закрепление фиксированного массива строк и получение char* для каждого индекса
I have to pass a pointer of type char* to a structure in C# and I can successfully do it with this code:
string myText = "Hello World"; fixed (char* ptrText = myText) { lvItem.pszText = ptrText; .... } However, I have to do this 20 times, and I would like to avoid pinning/fixing all 20 strings in a loop and instead populate them in an array of strings and just pin that array (seems more efficient), but I cannot get the part of pinning the whole array and then getting the address of each element as a char* pointer.
string[] arrStrings = new string[20]; fixed (string* ptrArray = arrStrings) { lvItem.pszText = &ptrArray[1] // this doesn't work .... } Anyone knows how is this done in unsafe context in C#?
