string syntax - C# / C Sharp

Hi I'm attempting to pass a string into another string but I get an error

This code work ok

jro.CompactData base(@"Provider =Microsoft.Jet. OLEDB.4.0;Data
Source=C:\Compa ct.mdb", @"Provider=Micr osoft.Jet.OLEDB .4.0;Data
Source=C:\tempd b.mdb;Jet OLEDB:Engine Type=5");

However when I declare a string and try to pass that I get an error

string mdbTemp = @"C:\tempdb.mdb ";

jro.CompactData base(@"Provider =Microsoft.Jet. OLEDB.4.0;Data
Source=C:\Compa ct.mdb", @"Provider=Micr osoft.Jet.OLEDB .4.0;Data
Source=mdbTemp; Jet OLEDB:Engine Type=5");

use the following:

jro.CompactData base
(
@"Provider=Micr osoft.Jet.OLEDB .4.0;Data Source=C:\Compa ct.mdb",
@"Provider=Micr osoft.Jet.OLEDB .4.0;Data Source=" + mdbTemp + @";Jet
OLEDB:Engine Type=5"
);

Hi jez123456,

You can never pass a string in another string. One have to concat two string
or format a string!

1) Concatenation

string mdbTemp = @"C:\tempdb.mdb ";

string target = @"Provider=Micr osoft.Jet.OLEDB .4.0;DataSource =" + mdbTemp +
@";Jet OLEDB:Engine Type=5"

OR

string target =
string.Concat(@ "Provider=Micro soft.Jet.OLEDB. 4.0;DataSource= ", mdbTemp,
@";Jet OLEDB:Engine Type=5"
jro.CompactData base(@"Provider =Microsoft.Jet. OLEDB.4.0;Data
Source=C:\Compa ct.mdb", target);

2) Formatting

string mdbTemp = @"C:\tempdb.mdb ";

string target =
string.Format(@ "Provider=Micro soft.Jet.OLEDB. 4.0;DataSource= {0};Jet
OLEDB:Engine Type=5", mdbTemp);

jro.CompactData base(@"Provider =Microsoft.Jet. OLEDB.4.0;Data
Source=C:\Compa ct.mdb", target);

String literal and const

char s = "This string literal"; or char *s= "This string literal"; Both define a string literal. Both suppose to be read-only and not to be modified according to Standard.
