Most omnipotent guru's,
New to c# and vb.net.  I need a very clear cut example of the VB replacement for lResult = instr("DogCatRatBat", "Cat") in c# and vb.net.   I've seen many vb.net/c3 semi-examples that feature looking for a single character and returning the ordinal position.  But I haven't found anything that simply returns the location of a simple multi-character substring within a string.  Can someone post a clear and complete example of what I need to have?

regards,

Ted

gmailjini - That was a good solution:

Example:
String str = "hallo world"
int pos = str.IndexOf("wo",0)

* The result would then be 7

nepuluz - I give you partial credit since you answered with in 3 minutes of gmailjini and your solution is so intriquing.

Thank you both!!

regards,

Ted
