I need to assign values to 2D array but I can't find the right syntax. I tried this but is't wrong:
string[][] s2d = new string[][] {
{"val1","val2"},
{"val1bis","val2bis"}
};
Thanks

You are almost there, just change the convention and use [,]., [][] used to define Array of arrays (Jagged arrays).
string[,] s2d = new string[,] {
{"val1","val2"},
{"val1bis","val2bis"}
};
If you want to enumerate on Multidimensional arrays you can do that but it is a flatten array.
foreach(var s in s2d)
{
// logic
}
Just access the elements in traditional way (if want).
for(int i=0;i < s2d.GetLength(0);i++)
for(int j=0;j < s2d .GetLength(1);j++)
var val = s2d [i,j];

My problem is the next foreach. See comment below. Thanks
You're using an incorrect syntax:
int[,] array2D = new int[,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };

I need to use in a foreach:
foreach (string[] s in sd2){}. With string[,] is not working.If you truly want a 2d array
string[,] s2d = new string[2,2] { {"val1","val2"}, {"val1bis","val2bis"}};
string[][] gives you a possibility of a jagged array

so you didnt want a array of 2d, you wanted a jagged array of any number of arrays.. thats a big difference

Yes, sort of. What I need, at the end, is a fast way to define a set of values on which do some operations: I need to create a bunch of nodes in an XML, and I use s[0]=nodeName and s[1]=value. The array-of-array is the fastest way i got to write code without replication.

Well this way you would use foreach ( string[2] s in sd2) which would give you s[0] and s[1]
If you really want array of arrays so declare array of arrays
string[][] s2d = new string[][] {
new string[] {"val1","val2"},
new string[] {"val1bis","val2bis"}
};
