Solution 1

(if I got you) Use String.Replace method to remove unwanted blanks (or whatever) from str1.

Dear Friend,

This will do:-

string.Compare(s1, s2, CultureInfo.CurrentCulture, CompareOptions.IgnoreWidth)

So if I want to find a string into other,What command I have to use to ignore character width(1 byte or 2 byte)?

I would start having a read of this MSDN article and looking at the examples.

MSDN String.CompareTo[^]

this shows that the ordinal position of the two string start in the same place

this is taken from the article

"
Remarks

The CompareTo method was designed primarily for use in sorting or alphabetizing operations. It should not be used when the primary purpose of the method call is to determine whether two strings are equivalent. To determine whether two strings are equivalent, call the Equals method.
"

So if you are after comparing the actual values look at using the Equals[^]
