DbConnectionStringBuilder::AppendKeyValuePair Method (StringBuilder, String, String)
Provides an efficient and safe way to append a key and value to an existing StringBuilder object.
Assembly: System.Data (in System.Data.dll)
public: static void AppendKeyValuePair( StringBuilder^ builder, String^ keyword, String^ value )
This method allows developers using a StringBuilder to create a collection of key/value pairs to be able to take advantage of the features included in the DbConnectionStringBuilder class when you add key/value pairs, without having to incur the overhead of creating and maintaining a DbConnectionStringBuilder instance. The AppendKeyValuePair method formats the key and value correctly and adds the new string to the supplied StringBuilder.
If some process has created a connection string, but now an application must perform a simple modification to that connection string, it may be more efficient to just add the key/value pair using a StringBuilder object. Instead of creating a new DbConnectionStringBuilder, developers can call the AppendKeyValuePair method, passing in a StringBuilder that contains the supplied connection string. The following procedure shows a simple example of this technique.
