Methods

AddDynamicParameters(object?)

Appends an object containing parameters to the dynamic parameters bag.

// Create a DynamicParameters object to hold the parameters.
var dynamicParameters = new DynamicParameters();
// Add parameters A and B to the dynamicParameters object.
dynamicParameters.Add("A", 1);
dynamicParameters.Add("B", 2);
// Add the dynamicParameters object to the builder.
AddDynamicParameters(dynamicParameters);
