Solution 1

try this.. :)

C#

System.Net.Dns.GetHostName();

or

C#

System.Environment.GetEnvironmentVariable("COMPUTERNAME");

gives you current pc name.. :)

C#

SqlConnectionStringBuilder connectionString = new SqlConnectionStringBuilder();
    connectionString.DataSource = System.Net.Dns.GetHostName();
    connectionString.InitialCatalog = "MyDatabase";
    connectionString.IntegratedSecurity = true;

And that has nothing at all to do with your original question. That is a separate question and you need to provide the proper description of the problem.

it should be, System.Data.SqlClient.SqlDataAdapter da = new System.Data.SqlClient.SqlDataAdapter("String Sql Query",SqlConnection Object);
