Use of fixed statement in C sharp

I am learning various programming language like C#, java, Visual Basic. Right now I am learning C#. I want to know how to use of fixed statement is in C#. I have referred different programming book but did not get suitable details. Please give me some details about the use of fixed statement. If you have any C# program for fixed statement then also let me know that. Thanks in advance.

The fixed statement of C# is utilized to check the variable repositioning using garbage collector. In C# the fixed statement is permitted only in unsafe context. The fixed statements are also utilized for the initialization of pointers. And for that you just require to make nesting of fixed statements. Observe following example:

fixed (int* pl1 = &pl.xa)

fixed (double* pl2 = &array[6]) // do something with pl1 and pl2

Try to understand following code which will show you the use of fixed statement in C#.

class Test
{
static string name = "xx";
unsafe static void F(char* p) {
for (int i = 0; p[i] != '\0'; ++i)
Console.WriteLine(p[i]);
}
static void Main() {
unsafe {
fixed (char* p = name) F(p);
fixed (char* p = "xx") F(p);
}
}
}
