Replace string field values ​​

This example shows how to force replace a specific character in all string fields. It gets all models in the project and returns the string if the field type is string.

public void ReplaceStrings(ICommandContext c, ICommandParams p) 
{ 
//Get all models 
var models = c.App.Workspace.CurrentProject.GetAllChildren(); 

//Process each model 
foreach(var model in models) 
{ 
//Get metaclass field information 
var fields = model.Metaclass.GetFields(); 

//Process only string type 
var strFields = fields.Where(f => f.Type == "String"); 
foreach(var field in strFields) 
{ 
//Exclude system fields 
if (field.Name.StartsWith("___") || field.Name.StartsWith("$") || field.HasTags("System,System.Core")) continue; 

//Get string 
var currentString = model.GetFieldString(field.Name); 

//Replace a string 
var replacedString = currentString.Replace("\v", "\r\n"); 
if(currentString != replacedString) 
{ 
model.SetField(field.Name, replacedString); 
} 
} 
} 
} 

The following example masks all string fields with ***.

public void MaskStrings(ICommandContext c, ICommandParams p) 
{ 
var models = c.App.Workspace.CurrentProject.GetAllChildren(); 

//Process all models 
foreach ( var model in models) 
{ 
//Get metaclass field information 
var fields = model.Metaclass.GetFields(); 
if ( fields == null ) continue; 

foreach(var field in fields) 
{ 
//Exclude system fields 
if (field.Name.StartsWith("___") || field.Name.StartsWith("$") || field.HasTags("System,System.Core")) continue; 

//Ignore non-string types 
if ( field.Type != "String" ) continue; 

//Mask strings 
model.SetField(field,"***"); 
} 
} 
} 

Hint

You can determine if a field is a system field by the following conditions:

• If the field name starts with ___ or $.
• If the field tag is set to System or System.Core

See the code below for reference.

IField field; 

//... 

//Exclude system fields 
if (field.Name.StartsWith("___") || field.Name.StartsWith("$") || field.HasTags("System,System.Core")) continue;
