Hi,
By using string.Compare and string.CompareOrdinal, you can check 2 string values.
So, practically by using string function will not solve your purpose.
You have to write a function to get what you want.
Here is the 2 overloaded methods
Ist method is simple expects 4 string values as argument
2nd method is little bit complex. You can compare any no. of strings by passing all the strings as array of string.
private int CompareAll(string str1, string str2, string str3, string str4)
{
if(str1==str2 && str2==str3 && str3==str4)
{
return 0;
}
else
{
return 1;
}
}
private int CompareAll(string[] Values)
{
string strTemp="";
foreach(string str in Values)
{
if(strTemp=="")
{
strTemp=str;
}
else
{
if(str!=strTemp) return 1;
strTemp=str;
}
}
return 0;
}
The code is in C#. If you want it in VB.NET, please let me know.
Thank you,
Sandip

Hi Sandip,
I am using vb.net, I had converted your first function into vb.net.
Your code is working fine, But I want to avoid the duplication. U R function is not avoiding duplication i.e; All the 4 strings must be different.
Please help me...
Thanks & Regards,
Sayeed.

Hi
I can give you logic but I am not sure about syntax
private int CompareAll(string str1, string str2, string str3, string str4)
{
dim strArray = new Array{str1, str2, str3, str4)
dim str as string;
str = strArray(0)
for (var i=1;i<=3;i++)
{
for (var j=i+1;j<=4;j++)
{
if (str == strArray(j))
{
return 0;
}
}
str = strArray(i+1)
}
return 1;
}
This should work
